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.

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.

I just want to be in the best shape I can be. Not to stand on that start line and say: 'Oh my God, I have this injury and that injury.' I just want to be able to go out and race.

I can swim I'm not bad, but not great.

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.

I deliberately returned slowly to training after Raphael was born and everything, apart from being bitten by a dog while out training in Monaco at the beginning of the year, has gone pretty well.

I can't imagine living and not running.
