Before competition, I start to question things. I don't know why it happens, but you've got to control it so you don't get too far out of the race.

Nothing means more to me than racing for my country, the Queen, the Royal Family, and the people back home that support me.

For 100 m., you have to go out fast but also bring it back, so we've been doing a lot of work on the back-end speed.

Kids are always going to be around people who break world records and that. It's how you deal with that. I never let it get in the way of my race, but I am always more than happy after the race to sign autographs and have photos.
