Usain St Leo Bolt OJ CD is a Jamaican retired sprinter. He is a world record holder in the 100 metres, 200 metres and 4 × 100 metres relay. Owing to his achievements and dominance in sprint competition, he is widely considered to be the greatest sprinter of all time.
A nine-time Olympic gold medalist, Bolt won the 100 m, 200 m and 4 × 100 m relay at three consecutive Olympic Games, although he lost the 2008 relay gold medal about nine years afterward due to a teammate's long-delayed doping disqualification. He gained worldwide fame for his double sprint victory in world record times at the 2008 Beijing Olympics, which made him the first person to hold both records since fully automatic time became mandatory. Bolt is the only sprinter to win Olympic 100 m and 200 m titles at three consecutive Olympics (2008, 2012 and 2016).
An eleven-time World Champion, he won consecutive World Championship 100 m, 200 m and 4 × 100 metres relay gold medals from 2009 to 2015, with the exception of a 100 m false start in 2011. He is the most successful athlete of the World Championships. Bolt is the first athlete to win four World Championship titles in the 200 m and is the joint-most successful in the 100 m with three titles.
