Usain Bolt renewed his claim as the world’s fastest man, powering Jamaica to yet another track and field gold medal by anchoring his country’s 4×100-meter relay team in its victory on Aug. 11 during the Summer Olympic Games in London.

Bolt now owns six career Olympic gold medals, with three won in 2008 and three won this summer.

His latest gold medal came in world record fashion as the relay team clocked in at 36.84 seconds, the fastest ever.

The U.S. 4×100-meter relay team, which featured fan-favorite Ryan Bailey, took silver with a time of 37.04 seconds, which matched the old record set by Bolt and the Jamaicans. Canada finished third, but was disqualified for crossing lanes, giving the bronze to Trinidad and Tobago.

Meanwhile, American runner Allyson Felix added her third Olympic gold medal this summer in her performance with the U.S. women’s 4×400 relay team.

Felix is now the first American woman to win three different track gold medals in the same Olympics since Florence Griffith-Joyner did it in 1988.

Felix ran with fellow gold medalists Sanya Richards-Ross, DeeDee Trotter and Francena McCorory, who combined for an easy first-place finish. Russia finished a full three seconds behind for silver, while Jamaica took bronze.

USA has now won five straight 4×400-meter Olympic medals, dating back to the 1996 Games in Atlanta.

“I think we were all pumped before this race,” Felix said. “There was a lot of emotion. We just wanted to close it out.”
