LONDON — Somewhere, some 8- or 9- or 10-year-old kid is in her or his backyard, throwing or running or jumping and dreaming big dreams about maybe someday being, say, Allyson Felix, lithe and elegant, or Tianna Bartoletta, fast and focused, or maybe Christian Taylor or Ryan Crouser, guys who produce when the spotlight is brightest.

Never, perhaps, has track and field found itself at such an intriguing intersection, indeed one suddenly filled with potential.

There are the kids, and their dreams. There is the sport, with its many documented woes. There is also, genuinely, because of the award of the 2024 and 2028 Summer Olympics, opportunity, and particularly in the United States.
