I remember watching the 2000 Sydney Olympics, with my nose right up to the screen, knowing there and then that I wanted a sporting career.

During an open water swim, it's easy to lose your direction. With all the splash, it can be quite hard to see the next buoy, so I look behind it for something bigger, like a tree or a building, and aim for that instead.

I raced in London in the 2012 Olympics, and it was incredible to be a part of, with half a million people watching and then later seeing kids going back to cycle.

The triathlon can be a very hard sport to train for. You see all the time when people try to improve - like their swim, for example: they train really hard for two to three weeks, and then when they go back to normal training, the swim goes back to where it was before.

I have more love, success, and security than I could ever dream of.

Success takes us to the top and away from those we love.

A startup is a company working to solve a problem where the solution is not obvious and success is not guaranteed.

Well, I think that there's a very thin dividing line between success and failure. And I think if you start a business without financial backing, you're likely to go the wrong side of that dividing line.
