Next month, the annual Tour de France starts from London. If you are a newbie to cycling, check out Eurosport's beginners guide.

You'll find everything about the green, yellow, white and polka dot jerseys, the points system, and general rules.

A few things I didn't know is that riders are not allowed to smuggle while passing customs, or hang on to the open window of a car. Nude cycling is also not allowed.
