Usain Bolt is a Jamaican runner and Olympic legend who has been called "the fastest man alive" for smashing world records and winning 7 gold medals as a reigning champion at the 2008, 2012 and 2016 Summer Games.
The 200-metre final went as scripted, with Usain Bolt proving his dominance yet again Thursday and Canada's Andre De Grasse delivering another message to the sprint world.
The Jamaican ran the 200 in 19.78 seconds to easily win his third straight Olympic title in the event, adding to gold from Beijing and London. It also brings his career gold medal tally to eight, including his 100 victory on Sunday.
Afterwards, Bolt declared it his last individual race at the Olympics ahead of his retirement next year. He can add another medal in the 4x100 relay final on Friday.
