I've no desire to do one of those 50-mile races like the Comrades or anything like that.
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.
If 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.
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.
I never plan to run at a certain pace. All my career my motto has been 'no limits.' I don't try to run with a set time in mind, sticking to set splits, because what happens if you're ahead of your splits - are you going to slow down?
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.
