In the final race, Usain Bolt, the clear favourite, had another world record-breaking run following his 9.58 second record in the 100 metres four days earlier. After having the fastest reaction time of the race, Bolt came out of the bend in first place and extended his lead further in the home straight, beating his previous mark of 19.30 seconds set at the Olympics by 0.11 seconds to take the gold medal and Championship record. Crawford, second fastest at the bend, was overtaken by Edward and Spearmon and eventually finished fourth. Edward vastly improved his previous best to set a South American record of 19.81, while Spearmon was third with 19.85 seconds. At 19 years, 255 days old, silver medallist Edward became the youngest ever world medallist for the men's 200 m.
