Oscar Pistorius

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 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.

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 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.

I have a strong sense that I have to educate people about disability.

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

I still find it strange, I suppose, when I say to someone, 'Can you just pass me my leg?' But I don't ever think about my disability.

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

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.

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 want to wake up every day and feel that I'm training harder than my competitors, that I'm dieting harder, that I'm recovering better. That's what gives me confidence when I'm lining up on the blocks. I've never gone out to prove people wrong. I just want to be the best that I can possibly be.

Out of the tens of thousands of prosthetic legs they've made, there's never been any 400-meter athletes run under 50 seconds. So, if this was such a technologically advanced prosthetic leg, then how come not everyone's qualifying, or coming close to the qualification time, then?
