My housemate, because I keep shrinking his jumpers in the wash.

My ex-wife, for the way I behaved towards the end of our marriage.

To anyone I’ve worked with between 5.30am and 8.30am. I am not a morning person.

I’m good at saying sorry – so no one, because I’ve already said it.

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.

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.

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 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?

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.

A road track car, a Porsche GT3. I’ve done the 24-hour race in Le Mans, which was a dream come true.
