Blake had made a slight movement but Bolt was the one who left his blocks, being immediately disqualified. In his absence, it was quick starter Kim Collins who led for the first half of the race. However, Blake was strongest in the second half, taking the lead and sprinting to win the gold medal with a time of 9.92 seconds into the −1.4 m/s headwind. Walter Dix made up ground on Collins, with the American edging into the silver medal position at the line by a margin of 0.01 seconds. At old, bronze medallist Collins became the oldest ever world medallist for the men's 100 m.
