The world’s fastest man remains untouched at the Olympics.
Usain Bolt of Jamaica won the men’s 100 meters in 9.81 seconds on Sunday night, becoming the first man in history to win three consecutive Olympic golds in the 100 meters. Carl Lewis is the only other man to have won back-to-back titles.
America’s Justin Gatlin, who won the 2004 Olympic gold medal before serving a four-year drug suspension for testosterone from ’06 to ’10, finished second in 9.89 seconds. He also finished behind Bolt for silver in the men’s 100 meters at the 2013 and ’15 world championships. At 34 years old, Rio could be his third and last Olympics. Canada’s Andre De Grasse finished third in 9.91.
The focus now shifts to the men’s 200 meters; Bolt, who has won the last two Olympic gold medals, will also be challenged by Gatlin at the distance. Bolt is the only man to have defended his gold medals in the 100 and 200 meters, so a three-peat would be unprecedented.
Bolt will also run the men’s 4×100-meter relay with his Jamaican teammates at the end of the Olympics. If he manages to win gold in all three races, his nine career gold medals would tie Paavo Nurmi and Lewis for the most by a track and field athlete. (Ray Ewry won 10 gold medals in his career but the IOC does not recognize the medals won at the 1906 Olympics, where he won two.)
Gatlin will also be a member of the United States’ 4×100 meter relay.
Bolt will turn 30 on Aug. 21 and has repeatedly said that Rio will be his last Olympics. He plans to compete at next summer’s world championships in London before retiring.
