Probably a train ticket anywhere in the UK.

I once bought the most expensive moisturiser in the shop and it brought me out in spots. Lesson learned.

A horse. I have two: Vesperal Dream and According To Sarah.

A Banksy painting.

Scotland’s rugby captain. My hero Gavin Hastings was captain when he came to our school for a training session when I was 10 or 11. I met him and was blown away.

The six Olympic gold medals, because at school I was never great at sport. When I look back on my career I think, how on Earth did that happen?

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.

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.

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.

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