Usain Bolt failed to make it to the finishing line in his last race.

The Jamaican great and eight-time Olympic gold medalist crumpled to the track because of a left leg injury as he was chasing gold in the 400-meter relay at the world championships.

Hours later, Bolt took to Twitter to thank those who wished him well after the injury.

Instead, Britain upset the United States to take gold in 37.47 seconds. The Americans were .05 seconds behind. Japan took bronze in 38.04.

Minutes earlier, Tori Bowie became the first double gold medalist at the world championships, anchoring the U.S. team to the 400-meter relay title ahead of Britain and Jamaica.

At the same time, Allyson Felix, running the second leg on the winning team, earned a record 15th medal at the world championships in a career going back to 2005.

Bowie, who won the 100 meters this week, ran a strong anchor leg, leaving behind the opposition to finish in 41.82 seconds.

Britain took silver in 42.12 and two-time defending champion Jamaica earned bronze in 42.19.
