Six-time Olympic champion Usain Bolt insisted he was a "clean" athlete and that fans of the sport could trust him despite recent failed drugs test by the Jamaican's sprint rivals Asafa Powell and Tyson Gay.
"There's a lot of things that haven't been said so I'm just waiting to see what happens," Bolt told a London news conference on Thursday, ahead of his return to the Olympic track on Friday where he will run in the 100 metres event at the Diamond League Anniversary Games.
"In life things happen and people make mistakes," said Bolt, who in London last year repeated his Beijing feat of winning the 100m, 200m and 4x100m Olympic gold medals.
"I was made to inspire people," added Bolt, 27 next month. "I was given a gift, I know I'm clean. For me it happens (failed dope tests), I'm not going to stress about it," added Bolt, the 100m and 200m world record holder.
