There's always going to be somebody who takes a dislike to you and you can't waste time worrying about it.

The biggest danger is trying to put too much pressure on yourself, trying to get in too good shape.

I don't feel guilty in having pleasure!

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

In the week before a race, I try to stay away from germ areas. I keep disinfectant wipes in my bag for when I have to use a supermarket trolley or something like that.

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.

In the marathon anything can happen.
