I knew I wanted to be a professional triathlete, but I didn't know it was possible until I won the junior champs. My dad said I should give Cambridge a go to see if I could do both, but it was only ever a trial.

We are quite different: I'm relaxed, and I get ready for races really late, whereas Jonny is really organised and punctual. I like to lead from the front in the run, whereas Jonny might hold back. Maybe it's because I'm the older brother, but I don't think there is a mental block that stops Jonny doing the same. I just think I'm a bit more gung-ho.

My first event was in Nottingham, aged 11, and the prize was a bike. I thought, 'Wow.' I had no idea what to wear. I think I did it in swimming trunks, then just put on a T-shirt and shoes for the bike part. Triathlons felt exotic. There was a technical and tactical aspect to it as well as the endurance challenge. I was hooked.

Schools are really, really important. It gives you access to every kid in the country. It gives you a massive pool of people to see who might be talented at different sports. It allows kids to try sports. Kids can be inspired all they want, but if they can't go out and try a sport, then it's no good.

I probably have more success in football, but baseball is a passion of mine, and I want to play as long as possible.

I love to eat. I could make a professional sport out of it.

Any time you factor in the enthusiasm that comes with college sports, it comes with a whole new level. It is less corporate, it's more of an unharnessed kidlike enthusiasm.

We work in a business where you feel you always have to say yes because you never know when you will work again. But I found myself questioning that paranoia, which I'd grown up with ever since I started working in the theatre in my late teens.
