Usain St. Leo Bolt OJ CD (//; born 21 August 1986) is a Jamaican sprinter widely regarded as the fastest person ever. He is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4×100 metres relay. He is the reigning Olympic champion in these three events, the first man to win six Olympic gold medals in sprinting, and an eight-time World champion. He was the first to achieve a "double double" by winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012), and topped this through the first "double triple" (including 4×100 m relays).
The 100 metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, it is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and 1928 for women.
The reigning 100 m Olympic champion is often named "the fastest man/woman in the world". Jamaicans Usain Bolt and Shelly-Ann Fraser-Pryce are the reigning world and Olympic champions in the men's and women's 100 metres, respectively.
A number of new world records were set in various events at the 2008 Summer Olympics.
