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?

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.

There is a big difference between being good and being great.

I'd like to show people that if you put the hard work in and you believe in yourself, then you can do whatever you want to.

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

Being disabled doesn't have to be a disadvantage.
