To my mum, for never being able to live up to what she would have liked me to be. She always wanted me to be a little princess and I was never going to be that.

My parents, for not pursuing an academic career.

My kids, for the jokes. Some of them are pretty bad.

To a resistant materials teacher at secondary school called Mr Noel. He had a comb-over and whenever he turned his back to write on the blackboard, we would roll up bits of paper and launch them at his head. Once, I hit him. I remember him turning around and looking crestfallen.

Jason Queally, a former teammate. He is older than me and was Olympic champion in Sydney. The way he mentored me, even though he knew I would be a rival, was amazing.

I just like to get to the start line knowing there was nothing else I could have done, that there wasn't a single session I didn't give 100 per cent. The physical certainty means you can relax mentally and let the performance come.

The London terror attack on 7/7 in 2005. I was in London the day before for the Olympic bid. When we won I thought, “I should stay over – it will be a great party tonight.” But I decided to go back to Manchester for training. Bombs went off on what would have been my route to the station.

Delivering papers in the freezing cold for my granny. I got paid in Panini football stickers, so it wasn’t all bad.

The real problem is that the pain actually gets worse. You have created massive acidosis in your muscles so there is a huge quantity of hydrogen ions and the pH in your blood changes. For 15 minutes you lie there thinking, "God, this is really bad. I'm going to die. It has never been this bad before." And every time you think exactly the same thing. You have to lie to yourself by saying you're not doing a second set. Then, without moving for 15 minutes, almost to the second, I would roll over and think, "OK, I think I can do a second set now." During those sessions I have never felt more alive or so close to death.

I don't enjoy it but I know that I have got to live with [myself] if I'm not going to give it 100 per cent. The key thing is getting to the start line and knowing that I couldn't have done any more, that I didn't back off. You accept the pain, because if you didn't there would always be that element of doubt.
