400 metres at the World Athletics Championships

The 400 metres at the World Championships in Athletics has been contested by both men and women since the inaugural edition in 1983. It is the second most prestigious title in the discipline after the 400 metres at the Olympics. The competition format typically has two or three qualifying rounds leading to a final between eight athletes. Jerome Young is the only athlete to be stripped of a medal in the event, as he lost his 2003 gold medal due to a doping ban.
