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

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.

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!

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.

Rio in four years; I've got more inspiration in the last two, three weeks. I'm sure I'm going to get more in the Paralympics in the next coming weeks, so by the end of this season, I'm going to take a month off, and then the next four years is going to be good.
