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

I have spent a very long time in Cate's shadow - she casts a pretty big one. I have always had the support of my family and coach, and they have always stressed we are completely different people and will achieve things in our own time. They stressed I would get my moment. I just had to be patient.

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 is a temptation for me to wear all my rings at once.

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 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.
