Usain Bolt emphatically confirmed his status as the greatest sprinter in history as he retained his Olympic 100m title in peerless fashion at London 2012, winning Sunday’s final in an Olympic record time of 9.63 seconds. The Jamaican, who holds the world record, finished ahead of countryman Yohan Blake and American Justin Gatlin. Seven of the eight finalists ran under 10 seconds in what was the fastest Olympic 100m final in history. But Usain Bolt came home first, clocking the second quickest time in history. Yohan Blake equalled his personal best of 9.75 in second, with Justin Gatlin also setting a new personal best of 9.79 as he took the bronze.
