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

The cheats always have a way of justifying their behaviour - everyone else is getting away with it, so why shouldn't I? But because they're so reliant on the drugs - and the drugs are not always perfect, you're not guaranteed to peak at a big event - they don't have the confidence to look in the mirror and know that they can go out and give their best. If you're clean and you've prepared well for a race, that's where you have an edge.

I actually got a nice surprise about being a mother because I expected it to be harder and to have to make more adaptations.

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.

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

At big championships it's not the fastest person, it's the person who gets it right on the day.

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