It's difficult, and it's an incredibly fine balance between getting your weight right down and being anorexic.
I may never get back to the track. The problem was that I was dominating my event, and the winning became slightly boring. I wanted new challenges, and I've got that on the road.
I always found that the more extreme and the more eccentric I was, that's what would separate me. I always felt that I needed that separation; otherwise, I'd just be like everybody else.
I just felt that if the team is doing seven hours, I'd want to do eight. I'd always need to do more. I knew that would make me better than everybody else.
Things change; your priorities change in life. So I'd never think of riding 100 miles on Christmas Day now, because I've got two kids, and it's selfish.
It's really incredible to win an Olympic Gold in your home city.
When you get into the final week of the Tour de France, it becomes a different kind of race. As the distance and the fatigue really tell, that is when it becomes a proper test of everyone's fitness.
You speak to the press at the Tour every day, but most often in a negative sense. Ninety per cent of the questions you are asked in the post-race press conferences are challenging or provocative, so you have to justify yourself; you have to try to give the right answers about every topic across the board.
