Whenever we race in London, the noise of the fans gives me goosebumps.

We're proud Yorkshiremen: we grew up fell running, and we still do it whenever we can. I did my first fell race when I was 11. It was a Tuesday night race called the Bunny Run, on a windswept moor above Haworth, and the prize was a chocolate egg.

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 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.

Give me anything that moves my heart, that gives me goosebumps.

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.'
