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. It's too easy to credit Pistorius' success to technology. 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.

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.

I think every athlete that’s just out here for the Olympics just does something to inspire those around them and inspire each other.

I have a phenomenal team behind me who have helped get me here and I, along with them, will now put everything we can into the final few weeks of preparations before the Olympic Games, where I am aiming to race well, work well through the rounds, post good times and maybe even a personal best time on the biggest stage of them all.

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.

I don't see myself as disabled. There's nothing I can't do that able-bodied athletes can do.

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.
