Usain Bolt, the world’s fastest man, has electrified the track with his blazing times and charismatic style. In 2002, at the age of 15, Bolt became the youngest world junior champion ever when he won the 200m title in his hometown of Kingston, Jamaica. But in his Olympic debut, slowed by a left hamstring injury, he failed to advance to the 200m quarterfinals at the 2004 Athens Games. Four years later, at the Beijing Olympics, he won three gold medals (100m, 200m, 4x100m), all in world record time. Then at the 2012 London Games, he became the first athlete to sweep the 100m, 200m and 4x100m at consecutive Olympics. He celebrates victories with his signature “To Di World” pose.
