It's definitely very special - right up there with running the world record,

It's totally different from last year because I came in with good shape with no health worries so it was about going out there and running well and enjoying it.

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.

I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.

I don't like going away from my children.

Never set limits, go after your dreams, don't be afraid to push the boundaries. And laugh a lot - it's good for you!
