There's no day when I don't think it would be great to be 25 years old and have the Olympics coming in less than 300 days - and be the best in the world. I can't think of anything so motivating.

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.

Kids are starting at such a low base rate in terms of fitness that it's taking them years to catch up to where people like me started from. Every little bit is making it more difficult for kids to succeed on a world stage.

I didn't even know what it was when I started. But I was lucky. I found it at 16. Most people don't discover decathlon until they're 21 or 22.

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.

I am an education ambassador, mainly working with schools.
