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.

To represent your country at a home Olympics is something special and I'm over the moon to be selected for Team GB. I was pleased to get the qualifying time in Berlin earlier this year and my sole focus is getting in the right shape for London.

From my training I can get a good idea of what I'm capable of.

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

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

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.

At big championships it's not the fastest person, it's the person who gets it right on the day.
