I don't want to be competing in a sport where I feel that I'm here not on my talent and my hard work but because of a piece of equipment.

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.

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

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.

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!

Everyone has setbacks. I'm no different. I happen to have no legs. That's pretty much the fact.

I wasn't happy with my performance at the World Championships in Daegu. I had an unbelievable race in the heats, but misjudged the semi and finished last.
