Usain St. Leo Bolt is a Jamaican retired sprinter, widely considered to be the greatest sprinter of all time. He is the world record holder in the 100 meters, 200 meters, and 4 × 100 meters relay. An eight-time Olympic gold medallist, Bolt is the only sprinter to win Olympic 100 m and 200 m titles at three consecutive Olympics (2008, 2012, and 2016). He also won two 4 × 100 relay gold medals. Bolt retired after the 2017 World Championships, when he finished third in his last solo 100 m race, opted out of the 200 m, and pulled up injured in the 4×100 m relay final.
