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.

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.

When you're walking into the stadium, you just say to yourself, 'the 100m is the same anywhere, the shot put is the same weight anywhere.'

Sometimes you have to resist working on your strengths in favour of your weaknesses. The decathlon requires a wide range of skills.

The stopwatch doesn't lie. The tape measure doesn't lie.

I don't even have my own computer.
