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

I've still got a small fitness and conditioning business where I travel round the world doing stuff for individuals and corporations, mainly fitness training.

Athletes these days are too robotic. People like to see performances filled with emotion. In my career I tried to be amusing, to differentiate myself from the other champions.

I am an education ambassador, mainly working with schools.

In my heart of hearts my motivation would always have been to be the best, and I think that athletics is probably what I was built for.

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.'

What used to drive me was the fact that I wanted to be better than everybody at something. One of my best qualities is that I used whatever other people found to be an adverse thing to be a positive thing for myself.
