The Honorable Usain St. Leo Bolt, OJ, C.D. (born 21 August 1986), is a Jamaican sprinter and a five-time World and three-time Olympic gold medalist. He is the world record and Olympic record holder in the 100 meters, the 200 meters and (along with his teammates) the 4×100 meters relay. He is the reigning Olympic champion in these three events.

Bolt’s personal best of 9.58 seconds in the 100 meters is the fastest ever legal time. Bolt also holds the second fastest time of 9.69 seconds (more precisely 9.683), the current Olympic record. Also, Bolt’s personal best of 19.19 s in the 200 meters is the world record.

The Jamaican relay team including Bolt, set the 4×100 meters world and Olympic records at the 2008 Olympics with a time of 37.10 seconds. This is the only run in the IAAF top ten performances which was not set by an American team.
