World's 100 meters fastest runner, Usain Bolt, Sunday retained his title, defeating America's Justin Gatlin at the world's championships in Beijing, China. Bolt raced past Gatlin at the halfway mark in a season's best of 9.79 seconds. Gatlin trailed in the second position at 9.83 seconds, taking the silver medal. Bolt struck a gunslinger's pose on the finish line, with a Bob Marley tune pumping out around the Bird's Nest stadium, where he had won the 2008 Olympics.
"I came out relaxed, no stress, and brought it home," said Bolt, who turned 29 on Friday. "It is all about running the race and getting it done. My aim is to be number one until I retire," the world's fastest man, Bolt, said.
