I have a very pessimistic view that every win takes you closer to a loss because no-one in the world can keep on winning forever.

It might sound stupid, but I don't enter a race to win - I enter a race because I love racing.

I think, for the benefit of our parents, the perfect night out would be when Cate and I touch the wall and we tie. This is what they dream - that we'll both win. Because then they don't have to pick a favourite child.

I find that after every win, there is a new surge in motivation because it feels so good. I am addicted to winning. That sounds terrible, but it is true you are addicted to that feeling.

I love standing up behind the blocks, and I love that moment just before you dive in and it goes quiet, and you take a deep breath and you just dive, and then you try and win, but that moment just before I go, that's why I race.

I collect rings from every country that I compete in, and I swap them around and wear different ones occasionally. I have about 10.
