New Delhi:Usain Bolt broke his own 100m world record to win Olympic gold in the blue riband event on Saturday.
After posting the second fastest time in Games history in his semi-final, the Jamaican timed an astonishing 9.69sec with seemingly effortless ease, ahead of Trinidad's Richard Thompson and American Walter Dix.
His time would surely have been even faster had he not eased up in the final 10 metres, opening up his arms and patting his heart as he crossed the line.
In one of the most eagerly anticipated races in sprint history, a record six of the eight finalists dipped below the 10sec barrier in the 91,000-capacity National Stadium, with Bolt's compatriot Asafa Powell only managing fifth.
Reigning double world champion Tyson Gay of the United States was not in the running after failing to qualify from the semi-finals.
