The only limitations are mental. The guy who thinks positively will win.

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

People tend to like an athlete's performance, but if you don't get a feeling for the individual, you're not very emotive about them.

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.

You can be an Olympic champion in 9.5 secs, but to be the greatest, there's more to it. It takes a bit of forethought and a lot of mental application.

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.

Most people doing the decathlon these days are quite boring, so people don't relate to them.
