I'd like to show people that if you put the hard work in and you believe in yourself, then you can do whatever you want to.

Putting on my legs is like putting on my shoes. I understand that's how some people might think differently, but I hope that in London, their perceptions open up.

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

The more I accomplish, the more pressure I put on myself.

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!

These have always been my legs. I train harder than other guys, eat better, sleep better and wake up thinking about athletics. I think that's probably why I'm a bit of an exception.

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.
