Usain Bolt reclaims world title in style

Usain Bolt regained his world 100 metres crown and restored some credibility to a sport tarnished by a plethora of doping scandals as he scorched to gold in 9.77 seconds at Moscow's Luzhniki Stadium on August 11, 2013.

Fast-starting American Justin Gatlin took silver in 9.85 with Jamaican Nesta Carter securing bronze in 9.95.

Disqualified from the 2011 final for false-starting, Bolt made no mistake out of the blocks this time and although trailing Gatlin, directly to his left, at halfway, he surged to the front at 60 metres.
