“The variety of training is a major selling point of triathlon. Different sports, different venues means it's always interesting, and you can always switch things round if the weather messes your plans up.”

“Alistair made my goals feel more achievable. I remember him competing for Great Britain when he was 15, and he came back with his GB kit. I thought, 'Wow, I want a part of that.' Sportsmen can seem distant, like superheroes. Seeing my brother achieve that made me think I could, too.”

“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.”
