The fastest man on Earth says there's no way he'll be caught up in a doping scandal.
FOX News Radio's Simon Owen reports from London:
Olympic champion Usain Bolt saying no matter how many doping scandals come and go, he is racing by the book.
(Bolt) "I was made to inspire people and to run. I was given a gift and that's what I do. And I know I am clean."
Bolt's Jamaican teammate Asafa Powell and his American rival Tyson Gay have failed recent drug tests, shocking the world of sprinting.
Bolt says there's no reason to question his record-breaking performances.
(Bolt) "If you were following me since 2002 you would know I've been doing phenomenal things since I was 15."
Bolt speaking here in London ahead of a track and field meeting, almost a year since he won three Gold Medals at the London Olympics.
