From my training I can get a good idea of what I'm capable of.

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

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 swim I'm not bad, but not great.

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

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.

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