London / Ostrava, August 6 (ANI): Usain Bolt retained his Olympic 100 metres title in spectacular style when the Jamaican scorched down the track in 9.63 seconds, the second fastest time ever run. Bolts 9.58 seconds in winning the 2009 world championship title is the only quicker time. His brilliant display proved he had completely recovered from the hamstring problems that had given a sliver of hope to his rivals. Bolt will now bid to complete an unprecedented double double by retaining his 200 metres title and will also seek a sixth sprint gold in the 4x100metres relay. Speaking to Reuters in June, Bolt had said that his only aim was to retain his Olympic titles in London in order to create his legacy.
