What's your favourite movie scene featuring cycling?
"I quite like American Flyers, where Kevin Costner does his sprint training with Eddie the dog. It makes me chuckle and I always think about it when there's a stray, angry dog on the road."
Who would play you in a film of your life?
"Sandra Bullock or Demi Moore."
Have you had any embarrassing crashes?
"I crashed into a pedestrian who suddenly walked across the road once. I couldn't get round him, clipped him and sent myself flying. It was two days before the 2009 Road World Championships started, so not the best time to wrench ribs and bruise my right hip."
Any advice for pedestrians, then?
"I wish pedestrians would actually look and not just listen to the road. You can't hear a bike coming."
What kind of music do you listen to when settling into one of those long training sessions?
"If I'm on the turbo in the garage, I just stick the radio on. I'm quite happy with my own thoughts and have spent seven hours over two days on the turbo with nothing but my own thoughts for company. I don't listen to music when I'm on the road because I think it's dangerous."
What's on the menu in the 24 hours leading up to a big race?
"Pasta and lots of water, then a big bowl of cereal the morning of the race."
"No! I've got enough to do on race day without them."
Who is your biggest rival going into London?
"When I started swimming it was a German called Claudia Hengst, but now I don't focus on anyone in particular. I just try to not let myself be my own nemesis."
