I apologise to people when I need to.

For an athlete, the biggest pressure comes from within. You know what you want to do and what you're capable of.

It's important that athletes can compete on a level playing field. And youngsters coming into the sport can know that if they are working hard and training hard, they'll see a true reflection of where they stand and what they can achieve worldwide and not be swayed by people who are cheating.

I can't imagine living and not running.

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 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.

Yeah, ideally, I'd probably wish to be more anonymous. But scrutiny and success go together. And I want to be successful.
