In my Olympic history I don't think I have achieved my potential as an athlete. That's what I want when I look back at my career. I want to be able to say I gave it my best shot.

I prefer just a women's race. It's a totally different game mentally.

I have not had the chance to go out there and do myself justice in an Olympic marathon yet. I have not been able to get to an Olympic marathon injury-free yet.

I try not to worry about things that I can't control.

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.

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.

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