I leaned too early. I was running, I looked across, I realised I was going to win - the thought I was on for a world record entered my mind - I reached for the line when I should have stayed straight.

My coach told me if I broke the national record for the 200, I could run a 100.

I remember once, actually the first race I ran, I fell.

I don't have a clue. These things don't bother me. I think about the technical stuff but not how many steps or what my heart rate is.

As long as I'm in good shape, you'll always see me smiling.

I am doing what I do [athletics] because the fans love it and it's a part of me, it's my personality. I think people come to see you run fast, but they also come to see a show, a performance. They want to see a personality, and that's what I give them.

When I was young, I didn't really think about anything other than sports.
