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.

My school career was absolutely crucial to me. As an endurance athlete, some of the most important years are maybe when you are 16, 17, and 18. For me, getting that right was very important, and my school allowed me to do that.

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.

Give your 100 per cent. Whether you are working or with family and friends. Even if you are sleeping, you should give it your 100 per cent.

Having support from family, friends - and now fans - definitely helps to affirm that I am worthy, loved, and beautiful. I hope everyone can see that in themselves and feel this way.

My passion lies in amazing, complex characters and really well-written stuff - not to say I wouldn't want to do a comedy if the right comedy came along... I'm an actor in Los Angeles, and I have a family I have to support.

I like to think I'm very grounded. I'm very grounded in my family. I'm very grounded in my community.
