The best thing about having your brother in the same sport as you means you can go out and train together every day, and we can push each other on. That's something many of our rivals don't have when training day in day out.
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.
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.
Whenever we race in London, the noise of the fans gives me goosebumps.
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.
