Usain Bolt Guards his Title and Wins Olympic Gold

Usain Bolt keeps his title of the fastest man as he sprinted to win an Olympic gold in the men's 100-meter race on Sunday with a record time of 9.63.

Bolt is first sprinter since Carl Lewis to defend an Olympic 100-meter race title, CNN said.

Bolt's season this year included defeats and injuries which had some worried about his performance at the Olympics, but he arrived to compete and ran the second-fastest time ever, which was even 0.05 seconds slower than his own record time of 9.58 seconds, BBC News said.

Despite his slow start from the blocks, Bolt finished first capturing the gold. Yohan Blake, countryman and training partner of Bolt won the silver and American Justin Gatlin won bronze, BBC News said.
