I met Bradley in Spain a few years ago and we hit it off straight away. At the start of this year Sky asked me to join them [to photograph the team in the tour]. It was a real privilege to be there when history was made. This was the first British winner. I think it works because you can see the camaraderie between the eight riders, summed up in the way they are holding each other’s shoulders and looking at each other. It shows that, ­although this is a professional sport, it is about friendship. They are like brothers in arms, really. There was only 20 seconds when they are all in a line - but I liked the haphazard nature of this shot. My only regret with it is you can only just see the eight rider. I never really thought this was one of my best, but looking at it in hindsight it's a nice shot. Sometimes you get a nice surprise. Photograph: Scott Mitchell #
