Usain Bolt wins 200 meters duel with Justin Gatlin in Beijing

Usain Bolt beat two-time drug cheat Justin Gatlin to secure the World Championship sprint double.

Four days on from riding to the rescue of his beleaguered sport in the 100 metres, the Jamaican attempted to make it four successive half-lap world crowns.

Gatlin, cast as athletics’ number one villain, again stood in his way but once more failed to wrestle away gold as Bolt held strong down the home straight to win with a world-leading 19.55 seconds.

Usain Bolt.

Pumping his fists before he'd even crossed the line.
