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.

I am also hugely excited to then be competing to defend my three Paralympic titles at the Paralympic Games. I believe we will see some amazing times posted and I am very much looking forward to what will be an incredible Olympics and Paralympics in London.

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.

The only disability in life is having a bad attitude

Oscar Pistorius is on the cusp of a paradigm shift in which disability becomes ability, disadvantage becomes advantage. Yet we mustn't lose sight of what makes an athlete great.

Through birth or circumstance, some are given certain gifts, but it's what one does with those gifts, the hours devoted to training, the desire to be the best, that is at the true heart of a champion.
