Usain Bolt has enjoyed an unstoppable career so far, rightfully earning the title of the world's fastest man. But how has he achieved it?
Born in Jamaica in 1986, the star's natural speed was noticed at a young age.
By 15 he was known as "Lightning Bolt" thanks to his triumph in the 2002 World Junior Championships. Here he won the 200m dash, making him the youngest world junior gold medallist ever. Later that year the IAFF awarded him their Rising Star Award.
Despite some setbacks - notably a hamstring injury that prevented him competing in the 2004 Athens Olympics - Bolt soon took the world by storm winning three gold medals at the 2008 Beijing Olympic Games.
Better still, he became the first man in Olympic history to win both the 100m (9.69 seconds) and 200m (19.30 seconds) races in world record times. He also helped smash the 4x100m relay with the Jamaican team in 37.10 seconds.
He defended his titles four years later at the London 2012 Olympics, becoming the first man to win gold medals in both the 100m (9.63 seconds) and 200m (19.32 seconds) at a consecutive Olympic Games.
