Where is the joy?

LAUSANNE, Switzerland — To use a favorite saying of Thomas Bach’s, the International Olympic Committee president, the IOC’s policy-making executive board and Bach himself did a great job — over three days of meetings that wrapped up Thursday — of talking the talk.

Amid corruption and doping scandals in, respectively, soccer and track and field, the IOC board and president talked up the import of maintaining — if not restoring — the credibility of international sport.

U.S. No. 1 overall — in fast-changing world

BEIJING — With images of Jesse Owens and Luz Long on the big screens, Owens’ grand-daughter kicked off the final night of the 2015 track and field championships by presenting Usain Bolt his gold medal from the men’s 4×100 relay the night before.

This was, in a nutshell, the past and present of the sport. The future?

Racing to a kidney transplant

BEIJING — These 2015 world track and field championships at the Bird’s Nest drew more than 1,900 athletes from more than 200 nations.

Every single one of them has a story. But no one has a story quite like Aries Merritt, your 2015 110-meter hurdles bronze medalist. In just a few days, he’s going to have a kidney transplant.

Rivals, respect: Bolt comes up big, again, in 200

BEIJING — Usain Bolt defeated Justin Gatlin in the men’s 200 Thursday night at the 2015 world track and field championships, running the best time in the world this year, 19.55 seconds, to win hands-down.

If the result of this big-time showdown had been the other way around, if Gatlin had won, would earthquakes and tsunamis roil the planet? Would sinkholes swallow up large towns? Meteors flash across the sky?

Red, white and maybe feeling blue?

BEIJING — Coming into these 2015 track and field world championships, it looked for — and to —  all the world like this could be the meet when the American team finally reached that elusive 30-total medal count.

With the meet now at its (just-past) halfway point, that looks exceedingly unlikely. The question now is more fundamental: is this 2015 performance a blip or a precursor for next year’s Rio 2016 Summer Games and, indeed, beyond?
