An Olympic medal won't define my whole life, although it might look like it to onlookers. When I look back, I should have been able to get an Olympic medal.

We, as athletes, have our suspicions about who's cheating, but I'm not convinced that the testing has yet caught up with what people are using or what they are using to disguise it.

Plenty of people who are 38 have run really well in the marathon.

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.

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

I prefer just a women's race. It's a totally different game mentally.

I try not to worry about things that I can't control.
