For an athlete, the biggest pressure comes from within. You know what you want to do and what you're capable of.

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.

I just want to be in the best shape I can be. Not to stand on that start line and say: 'Oh my God, I have this injury and that injury.' I just want to be able to go out and race.

Actually I don't choose to expose myself in public. I choose to compete; the other side just comes with the package.

If you look back at my marathons and ask whether I would swap one of them for my one balls-up, of course I would. But you can't choose. You have to make the best of it on the day.

You can't magic yourself back 10 years.

A half marathon is a good way to have a bit of fun and race against those girls and learn a bit more about them.The world half marathon is a world championship at the end of the day and it's important. I've win it twice and it's a quality event.
