Usain Bolt, the man nicknamed the 'Lightning Bolt', has struck gold again, smashing ANOTHER world record along the way.
Bolt's winning time of 19.30 seconds makes him the first man to break the world records in the 100m and 200m at the same Games.
He's also become the first man since Carl Lewis in 1984 to take the 100 and 200 gold medals at the same Olympics.
Silver and bronze went to Americans Shawn Crawford and Walter Dix.
Meanwhile, Great Britain's Christian Malcolm clocked 20.40 secs for fifth place.
