I've been to three Olympics and I don't feel I've ever quite achieved my best at any of them.

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.

Go in any direction..seeking out new sights just on the strength of your feet and the courage of your lungs.

I am not going to let Athens affect the rest of my life.

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.

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.

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.
