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.

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 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.

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.

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 don't want to be competing in a sport where I feel that I'm here not on my talent and my hard work but because of a piece of equipment.
