PARIS — When the athletes burst out of the blocks on Sunday morning in the second heat of the men's 110-meter hurdles, one of them moved with less urgency than the rest.
American Freddie Crittenden, the second-fastest 110 hurdler in the world this year, jogged his way through the heat and finished nearly five seconds behind the second-to-last competitor.
The decision not to run anywhere close to all-out was strategic, Crittenden explained afterward.
