Quotes from Jessica Ennis-Hill

I think that's one of the first things you'd say if you met me: that I am just nice and smiley. And that's how I might appear when I'm not competing. But I'm totally different when it comes to sport. It's just something that seems to be within me. It's not external or visual. But it's within me.

I love championships. That's when I want to be at my best. I love those environments. It brings the best out of me.

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 started training again four months after giving birth, and it was strange not to be fully in control - I'm so used to my body performing at a certain level, but it wasn't. I was like, 'Oh, man, can we go back to where we were, please?'

I don't know how long my body will allow me to compete, but I can't imagine doing anything else. That day will come, and I just hope there'll be a light shining down a path telling me where to go.

It's really important for me to look good before a race. I definitely think if I feel I look good, it makes me feel more confident.

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 started training with school friends and, one by one, they all dropped out. When we became teenagers, it seemed more exciting to go shopping at weekends. My mum told me not to worry about what my friends were doing and to stick at it.

There is a need to be the best you can be. You can't panic; you concentrate. When I run up to the hurdles, I'm very nervous, but I'll tend to think about technical things to keep my mind focused.

Some athletes feel they have to show they're confident and talk about what they're going to achieve. I don't think there's anything wrong with just quietly believing in yourself and just getting on with it. You don't have to talk about it all the time; you want your performances to show for it.

I've always known what I wanted. I've always wanted to be on top of that podium.
