I start planning then that's dangerous because then I have a target that I'm blinkered towards and I won't listen to the warning signs quite so much. I'd rather be in shape and then look around and say there's a race next week and jump into that than have it planned.

You see, with me, when I'm nervous, I smile and laugh.

I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.

An Olympic medal won't define my whole life, although it might look like it to onlookers. When I look back, I should have been able to get an Olympic medal.

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.

I have always run as hard as I can. You are not going to run any harder with or without men. You are running on your own two feet.
