There was a massive poster of me down my road, right outside the chip shop. I was about to go in, but then I saw it and changed my mind. Me coming out with a bag of chips, while I'm up there doing crunches on the poster... well, it would not look good.

I wasn't the kind of kid who would get A's without even trying. I had to work to get good grades, but I was very organised about it because I always wanted to do well at everything I did. I'm very competitive.

On a scale of one to 10, I'd rate my body confidence as a good seven. Everyone has their hang-ups, but I see my body as a training tool and I feel good about it.

People who aren't perhaps that into sport are going to be following me and wanting to be part of the Olympics. That definitely does bring added pressure but as an athlete the Olympics are the ultimate competition.

To get the adrenaline pumping between events - or to help me switch off, Jay Z, the Roots and Drake are on my playlist.

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'm proud of the way I've dealt with setbacks. It's hard when you feel down and you think, 'Why is the world doing this to me?' But you have to pick yourself up again. That's what makes you a better athlete.
