Putting on my legs is like putting on my shoes. I understand that's how some people might think differently, but I hope that in London, their perceptions open up.

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?

It's impossible to make everyone happy. Some will choose to see the negative. None is perfect but find a way of loving them perfectly!

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.

My parents didn't give me any scope to feel sorry for myself. They were just like 'go play with your brother, go climb a tree, go fall off your motorbike, do whatever you want. Don't come crying to us when you get scratched. You've got prosthetic legs - that's very nice.

To have been selected to represent Team South Africa at the London 2012 Olympic Games in the individual 400m and the 4x400m relay is a real honor and I am so pleased that years of hard work, determination and sacrifice have all come together.

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.
