A tour before Le Tour

We took Anya up Castle Hill, Cambridge to see the views over the city and were followed up by this crowd of tourists. They were enjoying a tour of the city the day before the Tour de France arrives here tomorrow. If you look carefully you can see the towers of King's College in the background.

I would love to go into town for the Tour but I'm not Sure Anya would appreciate it and I would hate to be stuck in traffic with her so we're going to visit a friend instead...
