This track story begins the same way most track stories of the past decade begin: A snapshot of Usain Bolt.
The Jamaican sensation, holder of three world records, was running his final race.
It was the final leg of the 400 relay at the IAAF World Championships in London, August 2017, and Bolt had just received the baton.
What happened next has been told and retold: Bolt jolted, gimped and fell with a left hamstring injury; he denied a wheelchair, limped across the finish line and ended a career in pain.
But in the background, Team USA finished second to Great Britain.
