Usain Bolt has one thing to say following the doping violations that have been publicized about his countrymen: “I’m clean.”Bolt, who is undoubtedly the fastest man in the world, is speaking publicly for the first time since Jamaican sprinters Asafa Powell, Sherone Simpson and Veronica Campbell-Brown tested positive for banned substances.“If you were following me since 2002, you would know that I have been doing phenomenal things since I was 15,” Bolt told reporters in London. “I was the youngest person to win the world junior title at 15, I ran the world junior record at 18, the world youth record at 17. I have broken every record there is to break, in every event I have ever done. For me, I have proven myself since I was 15. For me, I have shown I was always going to be great.”Bolt went on to say, “I was made to inspire people and to run. I was given a gift and that’s what I do. I’m confident in myself and my team, the people I work with. And I know I am clean.”Powell, Campbell-Brown and Simpson firmly deny knowingly taking banned substances. While those three will not be competing, Bolt is expected to run at weekend’s Diamond League meeting in London.Bolt’s speed is off the charts. See the video above.
