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. ”

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 was bribed into starting swimming with the promise of sweets and by being told that you can win medals. My mum had given me a bag of medals which she had won when she was young, so the idea of winning medals was very exciting. ”

I wanted to be an endurance athlete from a young age. I remember being in a careers class at school and saying I wanted to be a professional athlete and the teacher replying, 'You're not going to make it; it's not possible.' ”

London 2012 was the toughest time in our relationship but also the best. Things could get fractious - we were both competing for gold - but standing next to my brother on the start line for a home Olympics was so special. I remember saying: 'Let's go.' ”

As a family, we were always active. Lots of walking, lots of running as well as riding bikes with dad. ”

London 2012 was superb. It was the best triathlon experience in a million years. ”
