There's no quit in John Nunn

Forty-five years ago, at the Mexico City Olympics, a marathon runner from Tanzania finished dead last in the marathon. His name was John Stephen Akhwari. Akhwari had fallen and hurt his knee. He was bloodied and bandaged by the time he straggled to the finish line, more than an hour after the winner. There, he was asked by the filmmaker Bud Greenspan why he had not quit despite obvious pain.

"My country did not send me 7,000 miles away to start the race," Akhwari said. "They sent me 7,000 miles to finish it."

At the recently concluded world track and field championships in Moscow, the American race walker John Nunn fulfilled a mission that in many ways rivals John Stephen Akhwari's for passion and pathos.

And -- absolutely, though it might not seem it at first blush -- dignity.

In the 50-kilometer race walk, Nunn, dead last by about an hour, crossed the finish line in screaming pain. There, he collapsed and had to be carried off the track on a stretcher. Under the stadium, intravenous fluids were pumped into him. An attendant asked if he could take off his singlet and shorts. Nunn was in such pain he could not move. So, literally, his uniform had to be cut off him.

"I learned," he said, reflecting on it a few days later, "you just don't quit."

In the tightly knit race-walking community, Nunn's effort has already achieved a status approaching epic. Perhaps a few hundred people in Luzhniki Stadium saw it as well.

It deserves more.

Nunn finished 46th, in 4 hours, 34 minutes and 55 seconds.

The winner, Ireland's Robert Heffernan, had crossed nearly an hour beforehand, in 3:37.56.

The guy who finished 45th, Sándor Rácz of Hungary, had made it to the finish line some 22 minutes before Nunn, in 4:12.18.

For the last half-hour of John Nunn's ordeal, it was evident to the Luzhniki camera operators of the jumbo-screen TV that Nunn had set himself on a course of action and a test of will that was awful to watch and yet impossible to turn away from.

The cameras were on his every haunted step. Every time he winced or stumbled or grabbed his leg, it was all there on the big screen. Everyone among the few hundred stragglers at Luzhniki, it seemed, was crying out to him -- keep going.

By the time Nunn entered the stadium, the crowd was down to maybe 100 people. These 100 lived every moment of that last half-hour with him.  When he lurched across the finish line, collapsing, screaming, there were tears in the stands at what he had done and they had shared, all of them together.

"As soon as I finished," Nunn said, "my mind quit, and my body cramped up. They picked me up and I was just yelling. It was so painful. Tears were just pushing out of my tear ducts. They put me on a stretcher. They put me in some medical room.

They said, 'John, we had to take off your shirt so we can examine you. Can you take it off?'

I said, 'No.'

"Same with the shorts.

"So they cut off the shirt and the shorts.

"They put a towel on me. They put an IV in my arm. It took an hour, a full hour, for the intense cramping to calm down to where I could somewhat move."

The marathon -- 26.2 miles -- is usually thought of as the ultimate Olympic test.

The 50-kilometer race-walk is, in a word, harder.

While race-walking is keenly appreciated around the world, in the United States it is little known and mostly thought of as an oddity.

Which in itself is unusual. The odds of making the U.S. Olympic team in the race-walk -- if you can handle the mental toughness -- would appear to be better than in almost any other endeavor. There are untold numbers of 2:20 marathoners in the United States. And yet there are only a handful of guys who would even consider the 50k walk.

Nunn, for that matter, was the only American entrant in the event in Moscow.

The rules, it must be said, can take a little getting used to.

Walkers must keep least one foot in contact with the ground at all times. Two feet off simultaneously -- what would in ordinary speech you'd call  "running" -- is, in the jargon of race-walking, called "lifting," and grounds for a warning. Another rule requires straight legs at the point of first contact with the ground. If three judges give a walker warnings, the third warning leads to a disqualification.

It can all seem -- for those unfamiliar with the rules -- like a spectacle of sorts.

But make no mistake.

Race-walking can be, especially on a warm day like it was the day the 50k went down in Moscow, brutal. The physical demands are one thing. It's the mental grind that is the really hard part.

There are two Olympic-caliber distances, 20 and 50k.

A 50-kilometer race translates to roughly 31 miles.

For comparison, the marathon is 26.2 miles.

A world-class men's marathon is run in just over two hours.

A world-class men's 50k race-walk? Between three and a half and four hours.

The last American to win an Olympic medal is Larry Young, who won bronze in 1968 and 1972. In the U.S., funding is simply not a priority. The discipline has for years been kept alive in the colleges mostly at lower-level schools.

The results in Moscow showed exactly what happens when you invest time, effort and resource in race-walking programs and athletes. Eight different countries put athletes in the top 10.

Behind Ireland's Heffernan?

Russia's Mikhail Ryzhov finished second, in 3:38.58.

Third? Jared Tallent of Australia, 3:40.03.

Nunn's goal coming in was to try to finish in under four hours. A two-time Olympian, he raced the 20k in Athens in 2004 and then moved to the 50k in London last summer, the only American in the race, finishing in 4:03.28, in 43rd place.

It all started well enough for Nunn in Moscow, the kilometers clicking steadily by.

Indeed, through 20 he was hanging in there at a pace of under 5 minutes per kilometer. He turned kilometer 16 in 4:34.

At kilometer 23, though, Nunn started to feel some tightness in a hamstring. It got so bad he could not push off. He backed off. But it got worse. Then the pain moved down and around the leg, into his quadriceps, calf and shins. Then up, into his elbow joints.

"Everything started crunching down," he said. "It was miserable. It turned into Groundhog Day. Every step I was taking, I was, like, this is not going to end."

By kilometer 30, Nunn was doing roughly 6 minutes per kilometer. For conversion, 6 minutes per kilometer would see a jogger cover a mile in about 9 minutes and 40 seconds.

The debate started in his head -- to quit or not?

"At 25k," he said, "I thought, 'No way I'm going to get through this.' "

And this is where the thing gets truly fascinating. Like every racer in the 50k, Nunn went into it expecting pain. Maybe not so soon and not so severe. Even so, the race hurts. It's a given.

What to do?

"I would hit divots in the road. It would shock my body. My leg would go into an intense spasm of pain and lock up and double me over and I would, like, stop for a second or two and then keep moving. Other times, it would spasm so bad and I would try to keep moving but there would be 15 or 20 seconds of intense pain. Two or three minutes later, five at most, there would be the most intense cramping in my legs.

"I realized I would either fall over and be in total convulsion or not do anything and hit the finish line. I thought I would just keep going and see what happens."

Kilometer 44 would prove especially brutal. It took 7:42. More conversion: that would be a jogging pace of 12:23 per mile.

And still he kept going. "I honestly thought I was going to get told by the staff of the race I was going to have to finish out on the course, you are not going to finish in the stadium. But they never did tell me that."

He said, back now in the San Diego area where he is father to a 9-year-old, the two of them proprietors of a cookie business famous in track and field circles, "Part of me, at the end -- I remember when I finished the pain was pain I have never experienced in my life.

"There was a part of me that was crying out of humiliation. I was feeling like I was getting so much better," meaning at 50k strategy. "And then everything happened that day -- there was devastation at what had gone on.

"But in the 50k you just can't quit. Quitting became not an option. I know other people -- other people in the race said, 'I'm done,' and walked off long before the finish line. But USA Track  & Field paid for my airfare and training camp and for us to stay at a nice hotel."

And he said, in an echo of John Stephen Akhwari so many years earlier, "I had been asked to race the 50k. And so I did."

To quote Lenin, what is to be done?

It is good to be the king, and it is good -- unless and until there is evidence of doping, which it must be said could be tomorrow and could be never -- to be Usain Bolt. Because when you are Usain Bolt, you win, and when you win, you celebrate like he did Sunday at Luzhniki Stadium in Moscow, after yet another dominating performance by the Jamaican 4x100 men's relay team to close out the 2013 track and field world championships.

He shouted, "Moscow!" into the microphone. He threw his spikes into the crowd. Barefoot on the track, he did his "to the world" pose and performed his take on a Cossack dance.

Most important, later in the evening, Bolt -- perhaps alone among all the figures in track and field - has the gravitas to say what needed to be said about these championships. On a scale of 10, he said, they deserved a seven.

"It has been a different championships," he said. "But it has not been the best. It got better over the days. More people got more relaxed. More people started smiling. There were more people in the stands. It picked up at the end but at the start it wasn't as good."

He added, referring generally to the Russians, "They don't smile a lot but they're cool people … and there are lots of beautiful women."

The Russian journalists wanted more. "The food," Bolt said, "was always the same. And I'm used to going to the 100-meter final with a stadium that's packed, so that was different.

"So there were little things but nothing major and it was stuff that took me a while to get used to."

If Bolt weren't using the athlete access, he could have added that one entrance to the stadium was through a grass path by a parcourse set-up that was being used -- despite security restrictions -- by the locals. Or that access to the IAAF tent required going through not one, not two but three separate security stations -- all 20 feet apart.

Or that the wireless access in the press seating was completely worthless. And that the main press center was a half-mile away from the journalists' entrance to the stadium. The press bus stop was even farther.

Because Bolt doesn't have to worry about such things, it's not his problem that eating and drinking in Russia -- we're not talking alcohol, just regular stuff -- is super-expensive. A bottle of water can run 170 rubles. That's nearly $6.

Not to mention the controversy over Russia's anti-gay law, which erupted over Swedish high jumper Emma Green Tregaro's rainbow-painted fingernails and Russian pole vault champion Yelena Isinbayeva's comments about Russians considering themselves "like normal, standard people," and Russian sports minister Vitaly Mutko saying Sunday the law won't infringe on the private lives of athletes and fans at next February's Sochi Games.

In ways large and small, these championships set the stage for Russia to play host to the world in Sochi -- and, as they always do, fixed track's place in the world of sport for the here and now.

So -- what of track and field?

Track geeks know that the sport's next big thing is the world championships, in Beijing, back at the iconic Bird's Nest, site of the 2008 Games, in 2015.

That is two years from now. Two years is a very long time.

Until then, track and field will be pretty much -- at least for the casual fan -- off the radar.

That is, to be obvious, nothing short of a disaster.

Yes, track's governing body, the IAAF, puts on the regularly scheduled Diamond League series of meets, mostly in Europe, in the spring and summer. The IAAF deserves credit for that. But the meets are mostly relegated to -- to use a newspaper analogy -- the sports-section back pages.

Consider:

Soccer is on, and on television, pretty much somewhere in the world seemingly every day, and the World Cup will go down next year in Brazil. The NBA has made tremendous inroads all over the globe with a season that runs from October until June. American football has already started and won't conclude until February. Even the American baseball season runs from February until late October, sometimes early November.

The 2013 Diamond League will feature three more meets -- Stockholm, Zurich, Brussels -- but, unless there's a lightning strike like last year's 12.8 world-record by American 110-meter hurdler Aries Merritt at the Brussels meet, track won't get much worldwide attention absent -- regrettably, yet another -- doping scandal.

The best thing track has going for it is Bolt.

He says he is thinking about running at the Commonwealth Games, next year in Glasgow.

To be, once again, obvious: the more Bolt is on the track, the more track is on track.

To be even more obvious: every sport needs stars.

It would make for a great bar bet to see if the average person anywhere in the world could name even five athletes not named Usain Bolt who competed in the Moscow championships.

Here's the corollary to that bet: if asked to name a track or field star, that average person would probably say ... Carl Lewis ... or Michael Johnson. That shows you how much work track and field must do to bring itself out of its glory days and into the 21st century.

What Bolt didn't say about the Moscow meet, because it's not his job:

Great meets tend to produce world records. It just so happens that the swimming world championships in Barcelona immediately preceded the track meet in Moscow.

It is just four short years since the craziness of the plastic-suit era at the 2009 Rome world swim championships, when swimmers set 43 world records and experts were wondering if those marks would ever be threatened.

In Barcelona, the swimmers set six new world records, all by women. They set three in one day, the final Saturday of the meet. Katie Ledecky of the United States set two world records herself.

In Moscow -- no world records.

Sure, there were world-class performances in Moscow: three championship records, 16 world-leading bests, 48 national records. In all, 18 nations won gold medals, 38 won a medal of some color.

Those totals are all the more intriguing considering who didn't show because of injury (the likes of London 2012 men's 800 gold medalist David Rudisha) or doping (significant cases before the meet in Russia and Turkey as well as failed positives involving U.S. sprinter Tyson Gay and, among others, Jamaicans Asafa Powell, Sherone Simpson and Veronica Campbell-Brown).

FINA, swimming's governing body, introduced high-diving at the Barcelona championships. It was a huge hit -- action sports, if you will, for the water crowd.

The track championship is still the same meet it is, and has been, for years.

A few thoughts:

There's no rock or hip-hop music at a track meet the way there is at a baseball game, when a reliever is introduced in the late innings. What if, for instance, each of the sprinters in the 100, 200 and 400 was allowed to pick a riff by which he or she was introduced?

What about putting wireless in the stands -- in a robust way -- so that fans could really follow along on their cellular phones or tablets? The IAAF iPhone and iPad app, introduced before the Moscow worlds, was genuinely great. Who actually knew about it?

For that matter, nine days is too long -- way, way, way too long -- for this meet. Make it six, max. That's long enough still for the marathons, the distance events, everything. And if it's not, then it's time for some creative thinking about how to do this championship differently.

Every sport has to change, and grow. There are sound reasons swimming and gymnastics were elevated this year into the top rank of the International Olympic Committee's financial tier, along with track and field -- a slot the IAAF had for years occupied, alone.

Outside Luzhniki Stadium stands a statue of Lenin. Thus he -- in a matter of speaking -- oversaw everything here. So he and perhaps his most famous aphorism are worth bearing in mind as the IAAF and its stakeholders pack up and begin the two-year trek to Beijing, some serious thinking in order between now and then about what its proponents believe is -- and could again be for all -- the finest sporting endeavor humankind has ever dreamed up.

As Lenin said: what is to be done?

The sensation Brianna Rollins

It's an unusual thing, indeed, when Usain Bolt storms to victory -- this time, in the 200 meters -- and he is not the star of the show on an action-packed night at the world championships at Luzhniki Stadium in Moscow. That would be the new sensation of the women's 100 meter hurdles, Brianna Rollins of the United States, who -- in a race that many track aficionados had been looking forward to as the showdown of the meet -- came from behind to defeat the reigning Olympic champion, Sally Pearson of Australia.

Rollins' winning time: 12.44.

Pearson's: 12.5 flat.

Ponder this:

Rollins has made herself, in one year, NCAA champion, U.S. champion and, now, world champion. She finished up at Clemson this spring. She turns 22 tomorrow. She has now won 34 straight races, including heats, across four different disciplines.

Rollins ran an American-record 12.26 to win the U.S. outdoors in June. That 12.44 is her third-fastest time of the year even though it was run into a slight -- 0.6 meters per second -- headwind.

"I'd call it a great year for me," Rollins said. "I'd call it a blessed year."

As Benita Fitzgerald Mosley, the 1984 Los Angeles Games 100 hurdles gold medalist, now the U.S. Olympic Committee's chief of organizational excellence, put it in a telephone interview, Brianna Rollins "is something else -- she really is."

As for Bolt, who had dropped a starting block on his foot in the 200 heats but then got himself taped up and ran, anyway:

Sitting in the blocks, now his style, he got off to the slowest start in the field but nonetheless, as usual, had the race won by the curve. He eased up and still finished in 19.66.

By anyone else's standards, 19.66 would be extraordinary.

For all the understandable to-do about what Bolt does in the 100, the 200 always has been his best event.

To show how he has re-ordered time: 19.66 is his 10th-best 200 mark. Of course he holds the world-record in the event, 19.19, set at the 2009 world championships in Berlin.

Jamaica's Warren Weir, the London 200 bronze medalist, took second, in 19.79.

American Curtis Mitchell prevented a Jamaican sweep by coming on hard in the final 50 meters, finishing in 20.04 for third.

This is how close it was for third: Jamaica's Nickel Ashmeade crossed in 20.05 for fourth.

It was the first time in 200 history that all eight guys went a wind-legal 20.37 or faster.

Some more facts and figures to underscore not only Bolt's place in the record books but his hold on the imagination:

-- He became the first to win the 100-200 sprint double twice at the world championships.

-- His third 200 worlds gold surpasses Michael Johnson and Calvin Smith.

-- He now has seven world gold medals to go with the six he has won at the Olympics. A presumed eighth, the 4x100 relay, is coming up Sunday.

Pearson came into the women's 100 hurdles after overcoming an early-season hamstring problem. She ran 12.62 in the heats, then threw down a 12.5 in the semifinal, the fastest qualifying time, signaling that she was indeed ready to go.

Make no mistake: Sally Pearson is a big-game racer.

Rollins ran 12.55 in the heats, 12.54 in the semifinals.

This would be, of course, Rollins' first major international final. Also in Saturday's final: Dawn Harper, the 2008 Beijing gold medalist and 2012 London silver medalist.

In the first half of the race, it looked as if Pearson might just pull it off.

Rollins reacted horribly to the gun, 0.263. Pearson, meanwhile, got off to a good start, 0.154, and led through the first few hurdles.

But Rollins eventually made her move, passing Pearson over the eighth and ninth hurdles.

With the victory, Americans won both the women's and men's sprint hurdles at the worlds for the third time; David Oliver won the men's 110 hurdles on Monday. Americans won previously in 1995 and 2001.

"Today I didn't have the best start but I didn't panic," Rollins said. "I was just focusing on my own lane and working hard, trying to finish strong. Today was about the victory, not about the time. The fast times will come. I have a huge respect for Sally Pearson. She is a great athlete and it was great to compete with her today. I was nervous but nervousness is normal. It's just about the way you handle it."

For her part, Pearson said, "Of course you are going to a race to win but I am satisfied. It is not gold but the best I could produce tonight. It was a hard year for me. In July, others were smashing me. Tonight I was only beaten by one. Next year, I won't be getting any silver!"

Great Britain's Tiffany Porter ran a personal-best 12.55 for third place, Britain's first women's 100 hurdles medal at a world championships. Harper took fourth in 12.59, with another American, Queen Harrison, fifth in 12.73.

"It was a horrible race, and I don't know what happened," Harper said.

In other action, the illustrious Meseret Defar of Ethiopia won the women's 5000 meters, in 14:50.19, the fastest time in the race at the worlds in eight years -- despite a last 200 meters run in a relatively pedestrian 29.43.

Defar is 5-foot-3, 92 pounds of tough. Her record:

Three Olympic 5k medals -- 2012 and 2004 gold, 2008 bronze.

Five worlds 5k medals, a record -- two golds, one silver, two bronze.

In her typically understated way, Defar said afterward, "It is a big achievement for me."

Molly Huddle finished sixth in 15:05.73, the best finish ever by an American.

The U.S. women's 4x400 relay team's world championship winning streak -- five -- came to an end. Russia won, in 3:20.19. The Americans -- running without the injured Allyson Felix -- took second, in 3:20.41. Great Britain came in third, in 3:22.61.

In the women's high jump, Russia's Svetlana Shkolina, the 2012 bronze medalist, took gold Saturday at 2.03 meters, or 6 feet, 8 inches. American Brigetta Barrett, the London silver medalist, took second again; she cleared 2.00, or 6 6-3/4, but not 2.03.

"Two silver medals in the course of 12 months -- it's been one heck of a year," Barrett said later.

Finally, this:

Kenya's previous best performance at the worlds in any field event had been 15th in the triple jump qualifying.

In the men's javelin, won by the Czech Republic's Vitezslav Vesley with a throw of 87.17 meters, or 286 feet, Kenya's Julius Yego took fourth. He threw a national-record 85.40, or 280-2.

Mo Farah's double double-double

Distance running is a hard, lonely affair. The tell is the last kilometer. The crucible is the last lap. In our time, one man has emerged -- from among the Kenyans, the Ethiopians, the Eritreans -- to dominate, truly dominate, track's two distance events, the 5,000 and the 10,000 meters. He is Mo Farah, a global citizen who was born in Somalia, trains in Oregon, runs for Great Britain.

Farah won the 5,000 meters Friday night at Moscow's Luzhniki Stadium by the narrowest of margins, crossing in 13:26.98. In so doing, he won not just a double-double but has now performed an amazing double double-double.

That is -- he won both the 5 and 10k here in Moscow. At last year's London Olympics, he won both the 5 and 10k as well. At the 2011 worlds in Daegu, South Korea, Farah won the 5k; he lost the 10k by 26-hundredths of a second to Ibrahim Jeilan of Ethiopia, whom he beat in this year's 10k by two steps.

Only Kenenisa Bekele of Ethiopia has done the worlds double, in 2009. Bekele also doubled up at the 2008 Beijing Games. And the word "legendary" is typically attached to Bekele now as if it were his first name instead of Kenenisa.

"It was a lot harder work than last year." Farah said afterward. "I never thought in my career that I'd achieve something like this."

The finish of Friday's 5k was so fantastic that it was, genuinely, an instant classic.

Hagos Gebrhiwet of Ethiopia finished second, Isiah Kiplangat Koech of Kenya third. Both were timed in 13:27.26. They had to go to the thousandths to separate them: Gebrhiwet crossed, the clock said, in 13:27.259, Koech in 13:27.260.

It couldn't get any closer.

Of course, for track freaks it made for a sort of holy grail. But for anyone who appreciates will and effort, it shows why track can still claim such a powerful hold on the imagination -- and why, despite the malevolent ill of doping that has corrupted so much in the sport over the past several years, a race like Friday's 5k and its finish offers such tangible evidence of what it can still be all about.

It's three guys pushing themselves, to their limits, to get to the finish line first. Who wants it most?

Of course, this all assumes -- and there is no, repeat no, evidence to date -- that Farah is guilty of anything other than being very, very good.

With that caveat:

With three laps to go in the race, Farah went to the front. The others in the race lined up behind, among them his training partner, the American Galen Rupp, the silver medalist in the 10k in London.

A little math, for those unfamiliar with the 5k on the track.

A track is of course 400 meters. The 5000 -- this is fourth-grade math, but just to make it easy -- is 12 and one-half laps.

The races tend to start slow but then pick up toward the end. That, too, is only sensible.

A little more math, for reference:

The best 400-meter runners, like the American LaShawn Merritt, run championship races in about 44 seconds. A truly exceptional 400 winner goes 43-something.

What happens in the 5 and 10k is that after lap after numbing lap, the body starts screaming, "Stop - this hurts, and bad." That, though, is precisely when the best distance guys have to turn on the jets and run a last kilometer of about 2:20-something and a last lap of roughly 51 to 53 something. Anything less -- no chance.

In Farah's winning 10k in Moscow, he needed a 2:26.23 final kilometer to hold off Jeilan.

In Friday's 5k, he ran a 2:22.29 last kilometer. That is simply flying.

His last 800: about 1:51.

Last 600: 1:21.93.

Last lap: 53.51.

The difference between first and third in Friday's 5k, 28-hundredths of a second, is the smallest-ever in a world championships. The previous smallest differential: 33-hundredths, at the 2003 worlds in Paris.

Rupp finished eighth, in 13:29.87.

Farah also said this: "Anything is possible, I guess."

In other action Friday, Jamaica's Shelly-Ann Fraser-Pryce also doubled up, winning the women's 200 meters to go with the 100 she won Monday.

She became the first winner of the women's sprint double since 1991.

Fraser-Pryce made it look like a breeze: 22.17.

Murielle Ahoure of the Ivory Coast, the silver medalist in the 100, took second in the 200, too, in 22.32. They had to go to the thousandths in the women's 100 as well; Ahoure was timed in  22.313.

Blessing Okagbare of Nigeria, who is also having a fantastic meet, took third, also in 22.32; precisely, 22.319. Okagbare won silver in the long jump on Sunday behind American Brittney Reese, with a jump of 6.99 meters, or 22 feet, 11-1/4 inches. On Monday, she ran sixth in the 100, finishing in 11.04.

American Allyson Felix, going for a record fourth world title in the 200, didn't make it out of the curve, crumpling to the track, holding the back of her leg. She was carried off by her brother, Wes, who is also her manager; an ultrasound revealed a tear of her right medial hamstring, USA Track & Field announced.

She said later she was "extremely devastated" but in classic Allyson Felix form took the time and effort to nonetheless wish "all of my teammates the best for the rest of the meet."

The U.S. men's 4x400 relay won -- and the only drama was whether there would be a dropped baton.

There was not.

David Verburg ran a 44.37 to open things up. Tony McQuay, the 400 silver medalist, split a 44.68. Arman Hall ran 44.92. Merritt, the 400 gold medalist, ran 44.74 to close things down, and the Americans won by more than a second, finishing in 2:58.71, 2013's best time.

Jamaica took second, 2:59.88, Russia third, 2:59.9.

For Hall, it was his fifth world championship medal in three years -- 2011 world youth 400 and sprint medley relay champion, 2012 world junior 400 champ and 4x400 relay and, now, his first senior title.

The United States, minus Merritt, took silver in London last year.

Germany's David Storl defended his shot-put title with a throw of 21.73 meters, or 71-3 1/2, the first back-to-back winner since American John Godina in the mid-1990s. To celebrate, he put on a silly hat.

American Ryan Whiting came in second at 21.57, or 70-9 1/4.

Canada's Dylan Armstrong, with a throw of 21.34, or 70 1/4, got third. That medal is Canada's fourth, its best-ever total at a worlds.

In the men's long jump, American Dwight Phillips, 35 years old, the 2004 Athens Games gold medalist, four times a world champion -- most recently in 2011 -- had hoped Moscow would produce one final leap for the record books.

It was not to be.

The oldest man ever to jump in the final of a world championships, Phillips jumped 7.88 meters, or 25-10 1/4, on his third attempt. But he did not advance, and finished 11th.

"Today I gave everything I had, and it just wasn't enough," Phillips said. "Obviously I was looking for that storybook ending but I'm so proud of myself."

In the men's 200, Usain Bolt ran a 20.66 in the first round, 20.12 in the semifinals. The finals go down Saturday.

The heats of the women's 100-meter hurdles got underway with American sensation Brianna Rollins qualifying in 12.55.

Australia's Sally Pearson, the 2012 Games gold medalist, served notice that she may be -- finally in 2013 -- ready to rock with a season-best 12.62. Dawn Harper, the London silver medalist and 2008 Beijing gold medalist, got through easily in 12.84.

The 100 hurdles semifinals and finals are also set for Saturday.

Rainbow fingernails stir it up

There was a terrific track meet Thursday at Luzhniki Stadium at Moscow. But the central action came -- unsurprisingly -- courtesy of Russian pole vault diva Yelena Isinbayeva, underscoring the controversy over Russia's new anti-gay law. It all started when Swedish high jumper Emma Green Tregaro posted an Instagram picture of her fingernails painted "in the colors of the rainbow," with the hashtags #pride and #moscow2013. Also, Swedish sprinter Moa Hjelmer ran in the heats of the 200-meter heats with her nails painted in rainbow colors as well.

Isinbayeva, who got her gold medal Thursday after Tuesday's captivating pole-vault action, told reporters, in English, "If we allow to promote and do all this stuff on the street, we are very afraid about our nation because we consider ourselves like normal, standard people. We just live with boys with woman, woman with boys.

"Everything must be fine. It comes from history. We never had any problems, these problems in Russia, and we don't want to have any in the future."

Green Tregaro is one of the world's best jumpers, a consistent top-10 performer; she is due to return to the track Saturday for the high jump finals. Isinbayeva said even painted fingernails were out of place.

"It's unrespectful to our country. It's unrespectful to our citizens because we are Russians. Maybe we are different from European people and other people from different lands. We have our home and everyone has to respect (it). When we arrive to different countries, we try to follow their rules."

Isinbayeva's comments in defense of the Russian law, which prohibits the promotion of homosexuality to minors or holding gay pride rallies, need to be fully understood in context.

Who thinks that someone of her stature made such remarks without the full support beforehand of the leading authorities in Russia? After all, she is due to be the honorary mayor of the Sochi 2014 Winter Games athletes' village.

This, too: the demonstration by the Swedish athletes makes for an interesting test. There were no immediate reports of Green Tregaro being arrested. Nor, for that matter, Hjelmer.

Back to the track:

In the same way that Isinbayeva captivated fans Tuesday night with her victory in the pole vault, the men's high-jump thrilled fans Thursday, with Ukrainian Bohdan Bondarenko coming out on top in a duel with Qatar's Mutaz Essa Barshim, Canada's Derek Drouin and Russia's Ivan Ukhov.

For the first time since 1995, a 2.35-meter clearance in the high jump -- 7 feet, 8-1/2 inches -- would not even be good enough for a medal.

Bondarenko's winning jump: a championship-record 2.41 meters, or 7 feet, 10-3/4 inches.

Barshim and Drouin tied for bronze last year in London; here, Barshim took silver, Drouin, bronze. Ukhov, last year's gold medalist, settled for fourth. American Eric Kynard, the 2012 silver medalist, took fifth.

With a huge contingent of fans from Ukraine on hand, in their blue and yellow shirts, Bondarenko, seventh last year in London, made three tries at a new world record -- 2.46 meters, or 8 feet, 3/4 inch -- but no go. It was quite a spectacle; he wore one yellow shoe and one red.

In the men's 3,000-meter steeplechase, Kenya's Ezekiel Kemboi continued his dominance with an 8:06.01 victory.

If track and field were more of a mainstream sport, particularly in the United States, Kemboi would be a dream. As it is, in many precincts, he is a virtual unknown. Amazing, considering he has two Olympic golds and, now, three world championship golds.

For this race, Kemboi showed up with a Mohawk. He is a character and celebrated his win -- which he ensured with his typical kick into overdrive down the homestretch -- with, per usual, a dance, using the Kenyan flag as a makeshift skirt.

Under his singlet, it turned out, he was wearing a shirt that proclaimed he was wearing his victory -- he had a certain confidence, apparently -- to Kenyan president Uhuru Kenyatta and deputy William Ruto, "my heroes my kings I love Kenya."

Kenya's Conseslus Kipruto -- he's just 18 -- took silver, in  8:06.37, and France's Mahiedine Mekhissi-Benabbad bronze 8:07.86.

As a measure of their county's dominance in the event, check out the rank of Kenyans in top 10 in the order of finish: 1, 2, 4, 7.

Meanwhile, Evan Jager of the United States ran fifth in 8:08.62, the best finish for an American man since Mark Croghan in 1993. Jager's marked the fastest fifth-place time, ever, in a 3,000-meter steeplechase at a world championships.

Jager now has the three fastest 3k steeple times in American history. And he has only run the event 12 times.

"I'm definitely happy with how far I've come, and I'm excited for the future," Jager said. "But I really wanted a medal. I wanted it real bad."

Jehue Gordon of Trinidad and Tobago became the island nation's second-ever world champ -- behind sprinter Ato Boldon, now an NBC analyst -- winning the men's 400-meter hurdles, in 47.69, the fastest time in the world this year. American Michael Tinsley finished in a personal best 47.70.

Both men ended up sprawled on the blue track just after the finish line, the race too close to call for a few moments.

Serbia's Emir Bekric, the European under-23 champion who almost seems too big and too tall to be running track -- he looks like a linebacker for the Green Bay Packers, or something -- took bronze, in a national-record 48.05.

Felix Sanchez, the 2004 and 2012 Olympic champion, got fifth, in 48.22.

In the women's 400 hurdles, Zuzana Henjova of the Czech Republic, who had served notice all week that she was the one to beat, came through for the gold in 52.84, the best time in the world this year.

Americans went 2-3, Dalilah Muhammad catching Lashinda Demus at the line for the silver. Muhammad finished in 54.09, Demus in 54.27.

Caterine Ibarguen's win in the triple jump marked Colombia's first-ever gold medal at the worlds.

Finally, in the women's 1500 -- the start of which was held for 10 minutes while the men's high jump wrapped up -- Sweden's Abeba Aregawi kicked past American Jenny Simpson, who had led for most of the race.

Aregawi -- who ran for Ethiopia at the 2012 Olympics, finishing fifth -- crossed in 4:02.67, Simpson in 4:02.99. Ethiopia's Genzebe Dibaba took their in 4:03.86.

Simpson's silver proved emphatically that her victory in the event two years ago at the worlds in Daegu, South Korea, was no fluke.

"I think the last 200 I was almost unconscious," Simpson said. "I just kept telling myself, just run as hard as you can."

Mary Cain, the 17-year-old from Bronxville, N.Y., finished 10th, in 4:07.19.

She said, "I think later tonight I'm going to be really, really angry in a good way, and I think I'm going to be really motivated. I think you guys are probably a little scared. Normally you see me like, 'Oh, ducks, puddles,' but I'm going to go home and I'm going to get into this. I think this is going to motivate me so much for next year.

"Next year there are no worlds. It's just me and learning how to race."

Not yet a 'pregnant penguin'

MOSCOW -- The clock said it was a couple minutes past 10 in the evening. All the action on the track was over. The only matter left to be decided was at the pole vault, and there was only one jumper left. Yelena Isinbayeva had all of Luzhniki Stadium to herself. Just the way she likes it.

The greatest female pole vaulter in history, the first-ever in history to clear five meters, won the third world title of her incredible career, the only one in Tuesday's field to clear 4.89 meters, or 16 feet and exactly one-half of an inch.

The world record is 5.07, or 16-7 1/2. Isinbayeva made three tries as the clock ticked past 10. None were really close. No matter. The crowd came to see the Pole Vault Diva, Isinbayeva. They were thrilled, roaring at her every attempt, at what -- for the first time -- felt like a real world championships here at Luzhniki.

"I am so happy the era of Isinbayeva is back again," she said at a news conference that stretched into early Wednesday. "It was never finished."

Perhaps this is the last of Isinbayeva's world titles. Or not. She says now she is going to take what she called a "small woman's break," intending to have a baby next year. She is due to be the honorary mayor of the athlete's village at the Sochi 2014 Winter Games and said she intends to be walking around -- she really said this -- like a "pregnant penguin" offering the world's skiers and skaters "the traditional bread and salt" like a good Russian host.

The world has never seen anyone quite like Yelena Isinbayeva. And the scene at the pole vault runway -- Isinbayeva's catwalk -- capped a fantastic night of track and field, one that saw the U.S. team win four medals: one gold, three silver.

LaShawn Merritt simply blew away all comers, including London 2012 Olympic champion Kirani James, to win the men's 400 meters, in 43.74 seconds, 2013's best time. Fellow American Tony McQuay took silver, in a personal-best 44.40.

Luguelin Santos of the Dominican Republic -- 19 years old -- finished third, in 44.52.

James? An improbable seventh, in 44.99.

On his way out, James told Universal Sports, "I just died. I don't know what happened."

For Merritt, the 2008 Olympic champion, this marked redemption, and in a big way. He has overcome injury and the embarrassment of a ban relating to the purchase of a male-enhancement product at a convenience store and weathered it all with dignity. McQuay was far from alone when he said at a late Tuesday news conference that he considered Merritt a "great role model."

Merritt said winning Tuesday was a "sweet moment." He also said, "I guess you could call it a comeback. But I don't feel like I ever left. I always continued to work hard and keep faith in my ability -- spiritually, physically and mentally. To come here … I was ready for it."

In the men's 800, Nick Symmonds took silver, in 1:43.55, the best-ever finish in the event by an American and the first medal for a U.S. man since Rich Kenah's bronze in 1997.

Ethiopia's Mohamed Aman won, in 1:43.31 -- the 2012 world indoor champ adding the 2013 outdoor title to his collection. He is just 19. Djibouti's Ayanleh Souleiman took third, in 1:43.76, the first medal for his country since Ahmed Salah won silver in the marathon at the Tokyo worlds in 1991. Souleiman is just 20.

Well before anyone even got to Moscow, the 800 was going to be a wide-open affair. Not one of the three medalists from the 2012 Olympics was here. Gold medalist David Rudisha of Kenya, who set a world-record 1:40.91 in London, was hurt. So was silver medalist Nijel Amos of Botswana. Timothy Kitum didn't make the team Kenya sent to Moscow.

No one in the world had run under 1:43 this year.

In the heats and semifinals, astonishingly, all the Kenyans were eliminated. That meant that -- for the first time in the 30-year history of the world championships -- the men's 800 final would be Kenyan-free.

Symmonds had finished fifth in London; fifth at the worlds in Daegu in 2011; sixth at the Berlin worlds in 2009. He is 29. He had blogged before coming here about how significant it would mean to him personally and professionally to leave Moscow with what he called a "shiny medal" around his neck.

Coming down the stretch, it looked like it might be gold. But with about 20 meters to go, Aman proved just too strong.

"Nothing is impossible," Aman said. "You have to believe in yourself and train."

Echoed Symmonds, "To be a medalist takes a lot of hard work, it takes a lot of luck as well. A lot of experience. At the age of 29 ... it feels like all the hard work and the sacrifice has paid off."

All of that set the stage for the pole-vault drama.

There are three superb female pole-vaulters right now in the world. The American Jenn Suhr won Olympic gold, the Cuban Yarisley Silva silver in London. And then, of course, there is Isinbayeva -- the 2004 and 2008 Olympic champion who won bronze in London.

Isinbayeva is also the 2005 and 2007 world champion. But in Berlin in 2009, she no-heighted. In Daegu in 2011, she took sixth.

Last year in London, she was back to her old ways -- with that third. But for her, third is not -- well, first. And, as she acknowledged after the jumps were all over Tuesday, referring to the last few years, "Sometimes I was desperate … sometimes I thought I should quit."

When all three cleared 4.82, or 15-9 3/4, it marked the first time since 2007 that three women had cleared that height in the same competition. This was, in every way, world-class stuff.

Plus, the crowd was totally into it. The runway and pit were set up in what, in an American stadium, would be a football end zone. The stadium was not filled -- not quite -- but attendance was, because of Isinbayeva, eminently decent. Plus, because of Luzhniki's overhanging roof, the crowd noise was loud, indeed.

Isinbayeva would later say it was the best crowd support she had received. Ever.

"Yes," she said, through a translator in Russian, "that was the best-ever. It was my home crowd. I felt like I was at home. What can you say? Being at home helps you. If we had the Olympics in Moscow [instead of London], the results would be different.

"I've gotten support in other countries. But tonight I knew. Tonight, everyone was behind me. I felt all my emotions. I absorbed it. The support was just colossal."

To have the stadium all to herself? She smiled. In English, she said that was "nice feelings."

Suhr held the lead until she missed her first try at 4.89. Then the pressure was on.

Isinbayeva cleared.

Game over, pretty much -- though the other two women tried to clear, it was not their night.

Suhr took silver, Silva bronze.

Suhr called it a "great competition," adding, "If I was a spectator, that's exactly what I would want to see."

She also said, "When I think of where pole vaulting was and where it is now, you have to thank Yelena for getting us there. making the spotlight, making it one of the premier events to watch. Look at today. Every event was over but everyone stayed to watch it. We have to thank her for really paving the road for that."

People, the era of Isinbayeva is back again. For emphasis, it was never finished.

Empty seats everywhere

MOSCOW -- If Luzhniki Stadium were, say, Staples Center, you'd be tempted to say that the crowd that "filled" the seats for the third full day of the 2013 track and field championships was like something you'd see at a mid-season women's basketball WNBA game featuring the Los Angeles Sparks against, say, the Tulsa Shock. That underwhelming.

It was so disconcerting, in fact, that one American business executive sent a text message Monday evening to a reporter friend saying he had a section of the stadium all to himself.

This on a cool, beautiful night when Olympic champion Shelly-Ann Fraser-Pryce of Jamaica rocked the women's 100 meter finals in 10.71 seconds, winning by an almost unheard-of 22-hundredths of a second; American David Oliver made himself the comeback king in the 110-meter high hurdles in 13-flat; New Zealand's Valerie Adams proved herself, yet again, unstoppable in the women's shot put with a winning throw of 20.88 meters, or 68 feet, 6 inches; and more.

It's embarrassing, no two ways about it, and whether the blame is to be apportioned to the city of Moscow, the Russian government, the IAAF, the fact that it's summer and the Russians are quite naturally at their dachas and someone should have known that when they were planning a world championships for August -- whatever, it absolutely does not reflect well on what is supposed to be the No. 1 sport of the entire Olympic movement.

If it's this way here, in Moscow, it makes you wonder: what are the attendance figures bound to be in six months in Sochi, down in southwest Russia, for the 2014 Winter Games?

To be super-obvious: Moscow is one of the world's great capitals. Sochi is not. You can get to Luzhniki on the Moscow metro, one of the world's best. You get to Sochi, down in southwest Russia, on the Black Sea, by significant planning. The Sochi airport is not big. Only so many planes can land there in so many days.

These championships mark the beginning of Russia's so-called decade of sport. The 2014 Games will be followed by the 2015 swimming championships in Kazan and then, in 2018, soccer's World Cup.

One suspects the World Cup final, which will be back here in Luzhniki, will draw better than the track championships. Here, through three days, are the official numbers:

Saturday:

Morning -- 9,420

Evening -- 31,895

Sunday

Morning -- 12,861

Evening -- 40,461

Monday

Morning -- 9.350

Figures for Monday evening were not immediately available.

As always, the fine print:

-- The numbers are based on ticket scans at stadium gates. Someone who goes in and out multiple times counts only once.

-- Luzhniki is ordinarily an 81,000-seat stadium. As it has done in prior championships, the IAAF has blocked out blocks of seats to lower capacity. On Saturday and Sunday, capacity was 59,000 -- 43,000 spectators and 16 "accredited guests," meaning VIPS, media, athletes and others. On Monday, capacity was lowered further still, to 50,000 -- 34,000 spectators and 16,000 "accredited guests."

"It's dead. There's no atmosphere," Olympic champion Felix Sanchez told reporters after winning his 400-meter hurdles heat Monday morning.

"It's like day and night compared to London last year," he said, referring to the 2012 Summer Games.

As the attendance figures underscore, the contrast is especially marked in the morning heats.

In London, even the morning sessions were jammed. Here -- there are pockets of fans, in particular Ukrainians, noticeable in their blue and yellow, in the yellow, orange and red seats. Mostly, though, there are reporters and camera crews. Some are complete track junkies and love every single tidbit. Others are here on the off chance something unusual happens.

David Johnson, who runs the Penn Relays each spring and is here as a correspondent for Track & Field News, has been to every IAAF world championship since the first edition in Helsinki in 1983. He said of Moscow, "It feels like the smallest attendance, based on the men's 100 meters, in my experience."

That race, Sunday night, saw the stadium filled to roughly two-thirds capacity even though the biggest star in Olympic sports, Usain Bolt, was in the house. Bolt ran 9.77 to win; lightning struck at precisely the moment he crossed the finish line, creating not just one of track and field's but indeed all of sport's most iconic photographs in not just this but any year.

Luzhniki features an overhanging roof that circles the stadium. "Despite the size of the crowd," Johnson said, "the architecture of the stadium produces a noise beyond the crowd. It's the visual effect that's lacking."

That same overhanging roof, however, makes the scene -- particularly in the mornings -- even more eerie. The public-address system announcements ricochet, unintelligibly, around the empty seats.

Ticket prices started as low as 100 rubles, roughly $3. Even for Sunday night.

That's right -- you could have seen Bolt run Sunday night for 3 bucks.

Name a better deal in all of sports.

And yet -- the place could only manage two-thirds capacity?

Organizers allege that next weekend, which includes the four relay finals, is sold out. They also said before the event began that they had sold more than 80 percent of the ticket inventory.

Over the weekend, IAAF vice president Sergei Bubka, quoted by Reuters, said the weather might have been to blame:

"It was hot and very sunny and I know for Muscovites -- they always go to their dachas, they go outside, and maybe someone has bought a ticket and they don't attend.

"We insisted very seriously and very strongly regarding a promotion campaign and a lot of money was invested."

Journalist Elliott Denman has also been to every edition of the IAAF championships. A member of the U.S. Olympic track and field team at the Melbourne Games in 1956, he then turned to sportswriting and has been at the business -- one of the best -- for more than 50 years. He called attendance here at Moscow "sparse."

"Like everywhere," he surmised, "people have other opportunities."

Lightning strikes in 9.77

MOSCOW -- A few minutes before the men's 100 meter final here Sunday night, lightning began flashing in the sky over Luzhniki Stadium. Just in time for the Bolt show.

As the rain came down hard and fast, Usain Bolt rocked to victory Sunday night in the men's 100-meter final in a season-best 9.77 seconds.

Lightning flashed, literally, as Bolt crossed the finish line. Some things are just too fantastic for even scriptwriters to dream up. "I need to get that picture right now," Bolt said later. "That is pretty cool."

Track and field is, right now, in many ways, Usain Bolt. It made no difference that his winning time Sunday was not close to his world record of 9.58, not even close. Indeed, it marked only Bolt's sixth-fastest time. His time was, in fact, two-hundredths of a second slower than the fastest mark in the 100 this year, 9.75, run in June by American Tyson Gay, who has since reportedly failed more than one doping test. Gay has acknowledged that he has failed at least one test.

Just imagine if Tyson Gay had won this race. What if his doping matter had come out not before these worlds but -- after? What then for track and field?

American Justin Gatlin, who took second Sunday behind Bolt in 9.85, is the 2004 Olympic 100 champion but then served a four-year doping ban. What if Gatlin had won? What then for track and field?

The sport woke up Sunday to a report that Trinidad and Tobago's Kelly-Ann Baptiste, the  2011 world championship bronze 100 medalist with 2013's third-fastest time in the women's 100, reportedly failed a doping test and had withdrawn from the championships. "Drug Blow," screamed the front page of the Sunday Express, the West Indies' islands main paper.

The list of high-profile sprinters now known or believed to have failed doping tests this year alone: Gay, Baptiste and Jamaicans Asafa Powell, Sherone Simpson and Veronica Campbell-Brown.

Baptiste, as the newspaper noted, trains in Gay's group in Florida. Campbell-Brown and Gay are longtime friends.

Last week, Australian javelin thrower Jarrod Bannister was suspended for 20 months for missing three out-of-competition tests; French hurdler Alice Decaux has been provisionally suspended after testing positive for a supplement.

Forty Turkish track and field athletes have been suspended in recent weeks for doping. Several are just teenagers.

And then there is Bolt -- who has said up and down, this way, that way, every which way that he is clean.

Marion Jones said she was clean, too. So did Lance Armstrong. Everybody says they're clean -- until they're proven not.

“If you’ve been following me since 2002, you would know I’ve been doing phenomenal things since I was 15,” Bolt said last month in London. “I was made to inspire people and made to run. I was given a gift, and that’s what I do.”

Is Bolt the real deal? Is he, finally, the one star the world can believe in?

Or -- like so many other big names who have been unmasked -- too good to be true?

Time ultimately reveals the truth. Always.

Four of the five top finishers in Sunday's men's 100 were Jamaicans: Nesta Carter, who took third behind Bolt and Gatlin in 9.95, as well as Kemar Bailey-Cole and Nickel Ashmeade, both in 9.98.

This from a country that saw its national anti-doping agency perform a total of 179 tests in all of 2012, according to a letter published Aug. 7 in the Jamaica Gleaner. That letter, from the former executive director of the agency, sought to update the figure published in late July in the World Anti-Doping Agency 2012 global statistics database. That 106 figure, R. Anne Shirley said in the letter to the Gleaner, was mistakenly low, due to a reporting error.

All tests carried out by the he Jamaican agency, which goes by the acronym JADCO, were urine tests; JADCO performed not even one blood test, according to the letter.

Arguing that 179 is "somewhat better than what has been previously reported," the letter also said it's still "not as much as the agency or the Government would have/might have wished for …"

At a news conference late Sunday night, Bolt was asked about his connection with the German doctor Hans-Wilhelm Müller-Wohlfahrt, and whether he -- Bolt -- had ever used Actovegin, an amino acid preparation derived from calves' blood.

Actovegin is not on the WADA banned list.

Even so, WADA "closely monitors" its use. In part, that's because, for instance, Lance Armstrong and his team were regularly administered it on the grounds it was believed Actovegin would enhance a rider's performance, according to the brief against Armstrong filed by the U.S. Anti-Doping Agency.

"I don't know," Bolt said. "I really don't know the name of any substance. We just give that to my team. My team checks out any doubt. They clear it with everybody, make sure it's not on any IAAF, WADA [list] -- they have no problems with it."

So far, Bolt has had no testing problems.

Which leaves us with what we had Sunday in the rain:

Bolt, as ever, got off to a slow start. After the fiasco at the world championships in Daegu two years ago, in which he was disqualified for false-starting, it is his now way to stay in the blocks and make sure he starts safely.

Ashmeade, for instance, got out in 0.142 seconds. Bolt -- and Gatlin, too -- 0.163.

Gatlin went out hard. But anyone who has watched Bolt race since he burst onto the international scene big-time in 2008 knows that the last 50 meters are his for the taking, and that was the case Sunday as well.

Gatin acknowledged "feeling Bolt next to me" at about 45 meters. For his part, Bolt said, "I had to do what I do the last 50."

It was the sixth world title of Bolt's career -- two in the 100 (2013, 2009), two in the 200 (2009, 2011, with the 2013 race yet to come), two in the 4x100 relay (again, this year's relay still to go).

Of course, Bolt is the 2008 and 2012 Olympic champion as well as world record-holder in the 100, 200 and the 4x100 relay.

It is not just that Bolt wins but that he does it with such dominance. Here are the margins of his 100-meter Olympic and world championship victories:

2008 Beijing Olympics: .20.

2009 Berlin worlds: .13.

2012 London Games: .12.

2013 Moscow worlds: .08.

"I'm going to try to continue with these championships," Bolt said. "I want to be among the greats after I retire from track and field.

"Pele, Maradona, Muhammad Ali, all these guys -- I want to be mentioned among these greats."

For all that he has done on the track, Usain Bolt absolutely, unequivocally deserves to be mentioned among the greats. The challenge for Usain Bolt is that he is the best in his sport, and his sport greatly deserves special scrutiny.

"If he tests positive, he tests positive," Lamine Diack, the president of track and field's international governing body, which goes by the acronym IAAF, said recently of Bolt. "It would be a disaster for our sport but we would have to say he is positive.

"But I hope that doesn't happen because we don't need that."

A marathon, or an ordeal?

MOSCOW -- It is said by sport executives at the highest level, almost as if it is a prayer refrain offered in complete sanctification and utter devotion, that athletes are at the heart of everything they do. What to make -- once again -- of the women's marathon at the track and field world championships? The race, the first showcase event of the 2013 championships, started at 2 in the afternoon. The temperature at the start: in the mid-80s. Under an unrelenting sun, with no clouds in a high blue sky, it stayed hot throughout. The humidity: over 60 percent.

Forty-six women finished. Twenty-three did not. That makes for easy math: half as many did not even finish the race as did.

That's not a marathon. That's survival.

Edna Kiplagat of Kenya won the ordeal, in 2:25.44, becoming the first female back-to-back marathon world championship winner. Valeria Straneo of Italy finished second, 14-hundredths back. Japan's Kayoko Fukushi took third, in 2:27.45.

American Deena Kastor, the Athens 2004 Olympic Games bronze medalist, finished ninth Saturday in 2:36.12. Hours after the race, she would post to her Twitter account that it was the "hardest marathon ever," the word "ever" in all capital letters, adding that she couldn't walk on one foot and now had a "blood blister on my lip (of all places) and a horrible sunburn." She added this hashtag: #MyDermoWillHateMe

Why did this race start at such an absurd hour, in such ridiculous conditions? Consider this possibility: 2 in the afternoon in Moscow is 7 in the evening in Tokyo -- prime time Saturday evening viewing. And TV rights fees can be worth a lot of money, it's true.

On the one hand, what race organizers have asked the best female marathoners to run through in recent years at these world championships ought to forever put to rest any argument over whether women are tough enough to handle any and everything. On the other, going forward, organizers need a cold dash of common sense before something dreadful -- like, fatal -- happens.

The 2011 women's world championships marathon in Daegu, South Korea, went off with the temperature at 79 and humidity at 72 percent. At the 2007 race, in Osaka, Japan, the temperature was a searing 90; that race won by Kenya's Catherine Ndereba in 2:30.37, the slowest-ever world championship, hardly a surprise, seven minutes slower than Ndereba ran to win the 2003 marathon.

"I was just trying to endure the race, to get to the finish," Fukushi said after Saturday's third-place effort.

"The time of the race is unusual because I am used to run most of my races in the morning," Kiplagat said.

Chris Turner, a spokesman for track and field's governing body, the IAAF, pointed out that in Daegu and Osaka, some of those who did not finish -- colloquially known as DNFs -- had to be hospitalized because of the brutal conditions. "Here," he pointed out, "none of the DNFs had to be hospitalized."

It should be self-evident that "did not need to be hospitalized" should not be the baseline of running a world-class marathon.

The marathon served as the warm-up -- literally -- to the only final of the night on the Luzhniki Stadium track, Britain's Mo Farah's victory in the men's 10,000, and to Jamaican superstar Usain Bolt's first appearance in the heats of the men's 100 meters.

Bolt eased through in 10.07 seconds, the seventh-fastest time of the day.

"I didn't try to run too fast," he said later. "I was trying to work on my technique to get it right. Tomorrow, I will put more speed into it."

The semifinals and finals of the men's 100 go down Sunday. Bolt will be the huge favorite. Fellow Jamaican Yohan Blake, who won the 100 in 2011 when Bolt false-started, is injured. And American Tyson Gay is out because of a positive doping test.

In the men's 10k, in what proved to be a relatively slow and tactical race, Farah and Ethiopia's Ibrahim Jeilan dueled down the homestretch, just as they did in 2011 in Daegu.

Two years ago, Farah didn't have enough finishing speed. Last year in London, he proved he certainly did, winning not only the 10 but the 5,000 meters as well.

This year, he won by two steps, in 27:21.72. Jeilan crossed in 27:22.23.

Farah said later, "I was thinking on the home straight, 'Not again, not again, not again.' "

The victory now gives Farah the full set -- world and Olympic titles in the 5 and 10k. The only other man to win all four is Ethiopia's Kenenisa Bekele.

Farah is due to run the 5k next Friday.

Kenya's Paul Tanui finished third. American Galen Rupp, Farah's training partner and the silver medalist in London, placed fourth.

"I just didn't kick," Rupp said. "It's not that complicated."

In the mens' decathlon, Americans finished Day One 1-2.

Ashton Eaton, the London gold medalist, ran the 400 meters in 46.02, the fastest 400 ever at a worlds. That gave him a lead of 4,502 to 4,493 after five events over 20-year-old Gunnar Nixon.

Two-time defending champ Trey Hardee dropped out with a hamstring injury. He failed to clear a height in the high jump.

"I'm out there having fun -- no pressure," Nixon said.

Track's dirty day

When people ask, and they ask all the time, is track and field clean, there's only one answer. It came on a day like Sunday, when sprinter Tyson Gay, once among the poster boys for a U.S. Anti-Doping run-clean program, tested positive for a banned substance, and five Jamaicans, including gold medal-winning sprinters Asafa Powell and Sherone Simpson, also returned positive samples.

Those developments followed by just days word that the sport's governing body, which goes by the acronym IAAF, had stepped up its drug-testing program in Turkey amid reports of dozens of positive cases there, perhaps as many as 30, ahead of last month's Mediterranean Games in the city of Mersin.

Results in Turkey remain ongoing; under IAAF rules, a doping case can be announced only after a "B" sample confirms the initial positive finding of a failed "A" sample. Turkey has been hit by a rash of recent cases -- eight in June, including 2004 Olympic hammer silver medalist Esref Apak, and in May, allegations against London Olympic 1,500 meter champ Asli Cakir Alptekin and two-time European 100-meter hurdles champion Nevin Yanit.

The rash of positives Sunday comes just weeks after 2004 and 2008 200 meter Jamaican Olympic champion Veronica Campbell-Brown tested positive for a banned diuretic. Gay and Campbell-Brown are longtime friends.

Powell and Gay, to be clear, are among track and field's biggest names. For them to be busted, and on the same day, is -- there's no way around this -- a double dose of ugly news for a sport that just can't escape the perception that doping remains the fast lane to victory.

The world championships will be run next month in Moscow. Now they surely will go off under a shadow. A thread on the letsrun.com message boards proclaimed: "Admit it, we are all now waiting to see if [Usain] Bolt is positive … "

Bolt, the multiple Olympic champion, self-proclaimed "legend" and world-record holder in the 100 and 200 meters, has maintained to all skeptics that he is running clean.

As Adam Nelson put it in a Twitter post Sunday, "Drug testing detects the symptoms. We have a lot of work to do to fight the cause."

Nelson would know. He was made the 2004 Olympic shot put champ earlier this year after the guy who for nine years had won, Ukraine's Yuriy Bilonog, was finally caught. Bilonog had been doping.

Gay, 30, has run a 9.69 100 meters, the second-fasted ever -- tied with Yohan Blake, behind Bolt's 9.58.

A three-time world champion in 2007, Gay had often been plagued since by hamstring and groin problems. He came in fourth in the 100 at the London Games by one-hundredth of a second. This year, he had run the world's fastest 100, 9.75 in Des Moines at the U.S. nationals in June.

A few years ago, he was part of USADA's "My Victory" program, in which athletes pledged to complete clean. In his testimonial on that website, Gay said, "I compete clean because I really believe in fairness, and besides that, my mom would kill me! Just being honest."

He told Associated Press on Sunday that he had been notified late last week that a sample came back positive from a May 16 out-of-competition test, adding that he will have the "B" sample tested soon, possibly as early as this week. He said he had voluntarily withdrawn himself from Moscow.

It remained immediately unclear what Gay had tested positive for.

"I don't have a sabotage story," he said. "I don't have any lies. I don't have anything to say to make this seem like it was a mistake or it was on USADA's hands, someone playing games. I don't have any of those stories. I basically put my trust in someone and was let down."

Asked by AP who that was, Gay said, "I can't really say it. Sometimes a human being naturally, generally trusts somebody. That's what people do."

USA Track & Field chief executive Max Siegel said in a statement, "It is not the news anyone wanted to hear, at any time, about any athlete."

Powell, for his part, held the world record -- running a 9.74 in 2007 -- before Bolt started his assault on the mark. Powell is still the fourth-fastest man all time and holds a gold medal as part of the Jamaican 4x100 2008 relay team.

Powell has run 9.88 this year. Even so, he did not make the Jamaican team for Moscow.

He and Simpson reportedly tested positive for the stimulant oxilofrine, and Powell issued a statement in which he denied being a "cheat."

It said, "I want to be clear in saying to my family, friends and, most of all, my fans worldwide that I have never knowingly or willfully taken any supplements or substances that break any rules."
