I've always been good at putting things behind me–I fall apart, do my crying bit, and then put it away and move on.

I have always loved running on the roads, ever since I used to take part in relays for my club when I was 12 and 13. I felt really at home on the surface.

The cheats always have a way of justifying their behaviour - everyone else is getting away with it, so why shouldn't I? But because they're so reliant on the drugs - and the drugs are not always perfect, you're not guaranteed to peak at a big event - they don't have the confidence to look in the mirror and know that they can go out and give their best. If you're clean and you've prepared well for a race, that's where you have an edge.

No one remembers who came fourth.

I have been doing 120 miles a week, when normally I would do about 140.

I'm confident of what I have to achieve in the buildup to London 2012.

I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.
