Bolt: people still doubt me

USAIN BOLT, the world’s fastest man, believes it will take time for people to believe that his performances are possible without doping.

The 23-year-old Jamaican, who won three Olympic titles in world record times in Beijing last year, clocked the fastest 100metres ever recorded in Berlin in August, winning the World Championship title in 9.58 seconds – an astonishing 0.11secs faster than his previous world best.

People have watched in disbelief since Bolt set the world record in only his fifth 100m race at the Reebok Grand Prix in New York on June 1, 2008.

And he has once again reiterated that he does not use performance-enhancing substances and believes he will confound the doubters by continuing to run quickly.

“I’ll continue running fast, I am clean without a doubt,” said Bolt, who has four of the 10 quickest 100m times in history and five of the top-10 200m times.

“As soon as you start running fast there’s going to be a problem.

“It’s going to take a couple of years for people to start believing that you’re actually clean.”

Bolt, who was speaking in London is also confident of defending his Olympic titles in 2012.

“The Olympics here are going to be a very big thing for me because I did extraordinary things in Beijing,” he added.
