I'm competitive - that's what defines me - and I love it.

There were only ever two black kids at my school. I never considered myself to be 'a black kid'. I was who I was. Which isn't to say things haven't happened to me that wouldn't have happened if I wasn't black.

Sport fosters many things that are good; teamwork and leadership.

For kids it's natural to be competitive.

In sport, if you want to be the best you have to compete against the best - I would much rather have come tenth and be judged against everyone than come first and be judged against just a few.

I was in the doldrums for a while after my athletics career ended in 1992. I spent six to eight hours a day training, for 18 years, and it took a long time to get over the regret that I wasn't competing in major championships any more. All I ever wanted to be was the best. But I find new projects and I keep things in perspective.

Retiring was hard. I'd spent 15 years doing something I loved, but when you get older everything seems to go. When I started spending too long with the physio and the doctor, I knew it was time to call it a day. But I had no preparation for being retired and I didn't know what to do.
