Usain Bolt retains his 100m title in an Olympic record 9.63 seconds

Usain Bolt, 27-year-old Jamaican tonight fulfilled his dream of becoming a “legend” of the sport by successfully defending his Olympic 100m title.

The world’s fastest man turned on the afterburners at about the 50-metre mark and simply buried a star-studded field of sprinters to become the first man since Carl Lewis in 1984 and ’88 to win back-to-back Olympic 100-metre titles.

He set the new record of 9.63 seconds- topping his Beijing Olympic record of 9.69 but leaving his 2009 world record 9.58 intact.

After the race, he said, “I knew it was going to be like this. There wasn’t a doubt in my mind it was going to be like this,” Bolt said.
