I did my first cross country race when I was about 10 and absolutely loved it. I wasn't particularly good, so I didn't just carry on because I was good, but it just really appealed to me.

I did a term at Cambridge University studying medicine, so I could potentially have followed in Mum and Dad's footsteps and become a doctor.

It's good to put on some lube under your wetsuit, so I tend to use a lot of baby oil on my arms and legs. It stops you chafing and helps you get your wetsuit off after the swim.

Triathletes can push themselves quite hard, and I have seen people collapse on a barrier or pass out on a bike.

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.

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.
