Grenada's Kirani James adds the 400m title to his World Championship crown

World champion Kirani James wins Grenada's first ever Olympic gold medal with a stunning 400m victory at London 2012.

James said: "It means a lot. Grenada will be going crazy right now."

Since 2008, James has won Commonwealth Youth gold, World Youth gold, the World Juniors, World Championships and now the Olympics. With this display, he becomes the eighth fastest man in history over one lap. This is a new generation of 400m men. In an event traditionally dominated by the United States, not a single American made the final.
