I just love thinking about what makes people tick

I don't want to think of life after competing. But if I were to do anything else I'd go down the psychology route. That's what interests me.

I want to experience that massive adrenalin rush when you step into a new stadium, all the more so when that Olympic Stadium is packed full of people waving British flags.

I do watch what I eat but I've got a real sweet tooth.

People think the gold medal is yours and they say you're going to win - but they have no idea how hard it is. People aren't doing it negatively - they're mostly lovely and they really do want you to win - but they don't understand the difficulty and intensity of competition.

We always spend more time on the throwing events and a little bit more on the long jump. They're my weaker events - they don't come as naturally to me as running and jumping. I like the hurdles and the high-jump, I'm a springy, speedy athlete so those suit me.

I learned what I need to do in the long jump, what I needed to do in the javelin and I've been able to rectify those events. It's been a bit of a learning curve, which is good.
