Usain Bolt 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 1977. Along with his team-mates, he
also set the world record in the 4x100 metres relay. He is the
reigning Olympic champion in these three events, the first man to
win 9 Olympic gold medals in sprinting, and a eleven-time World
champion. He was the first to achieve a `triple-triple' by winning
100m, 200m and 4x100m relays titles at 3 consecutive Olympics
(2008, 2012 and 2016).
His 2009 record breaking margin for 100 m, from 9.69 (his own previous world record) to 9.58, is the highest since records began.
