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

I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.

You can't become a winner overnight, or even in a couple of years-it takes time... You will lose races and you will have to accept that, learn from it and believe that you'll win the next one, knowing that you'll probably lose that as well. All the time you have to keep believing that one day you will win.

I set myself some specific goals, but the key one is just getting myself into as good a shape as possible for one day this year: the Olympic marathon.

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.

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