Jamaican Usain Bolt smiles as he looks back while winning the 100-meter semi-final race at the Summer Olympics in Rio de Janeiro, Brazil, on 14 August. He finished the race in 9.86 seconds.

Bolt went on to win a gold medal in the finals, becoming the first athlete to win three Olympic 100-meter titles. He also took gold in the 200-meter race and 4x100-meter relay, thus obtaining the ‘triple-triple’: three sprinting gold medals in three consecutive Olympics. Bolt later lost this status, after a teammate was found guilty of a doping violation and the 2016 Jamaican relay team was stripped of its gold medal.
