I know I'm Clean - Insists Bolt

Usain Bolt was overwhelmed  with questions prior to this weekend's Diamond League meeting in London where the 6 time Olympic champion will race in 100m.

"I think there are a lot of details that are still to be discussed, a lot of things that haven't been said so I'm just waiting to see what happens," Bolt told before  Meeting in Hotel.

"In life things happen and people make mistakes but as an athlete you have to be very careful and aware, it's hard but that's why you have a team to have to help you out with these things,"

Asked if the public could trust him, Bolt rolled his eyes and set about his now familiar refrain.

"I was hoping that question would come later in the day," he said. "How long have you been following me - since 2008 maybe?

"If you were following me since 2002 you would know I've been doing phenomenal things since I was 15 and setting records all the time.

"I was made to inspire people and to run I was given a gift and that's what I do. I'm going to continue running and using my talent and help the sport.

"I'm not going to stress about it (doping). I know I am clean and I just want to improve the sport and that is what I am going to do."
