You don't call the witness a liar, not while he is in the witness box.

My parents didn't give me any scope to feel sorry for myself. They were just like 'go play with your brother, go climb a tree, go fall off your motorbike, do whatever you want. Don't come crying to us when you get scratched. You've got prosthetic legs - that's very nice.

If the legs did provide such an advantage that some of the people are claiming they did, then there would be a lot more amputees using the exact same prosthetic legs I have, running the exact same times I have - and that's not the case.

I can have my goals, and I can have my dreams. My goal is to make the finals and improve my position. I want to run all decent races. I don't want to look back and say I ran a terrible race.

Thank you to everyone that has made me the athlete I am! God, family and friends, my competitors and supporters! You have all had a hand!

I have a phenomenal team behind me who have helped get me here and I, along with them, will now put everything we can into the final few weeks of preparations before the Olympic Games, where I am aiming to race well, work well through the rounds, post good times and maybe even a personal best time on the biggest stage of them all.

When you're competing, you don't have the choice of what the weather will be like. It really doesn't affect me. I ran one of my fastest times in the New York Diamond League meeting last year. It was raining pretty hard then.
