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

I think your body is just a little bit stronger after pregnancy.

I don't like going away from my children.

You can be strong and true to yourself without being rude or loud.

There's always going to be somebody who takes a dislike to you and you can't waste time worrying about it.

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.

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