I've been followed home late at night. I've been shot at on the highway.

I want to wake up every day and feel that I'm training harder than my competitors, that I'm dieting harder, that I'm recovering better. That's what gives me confidence when I'm lining up on the blocks. I've never gone out to prove people wrong. I just want to be the best that I can possibly be.

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.

I made the mistakes not because I'm tired.

Being disabled doesn't have to be a disadvantage.

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 have run two Olympic 'A' standard times over the past 12 months and with the time I ran at the African Championships last week I know my speed and fitness are constantly improving so that I will peak in time for the Olympics.
