The tour lasts about three weeks. At the end of each day's race the leader is given a yellow shirt, the best sprinter is given a green shirt, and the best rider in the mountain races is given a polka dot jersey. He is sometimes called the King of the Mountains. The best young rider, who must be under 26, gets a white jersey. The winner is the one who finishes the race to Paris in the fastest time. There is a lot of prize money for the teams of the winners of the Tour, but the winner of each day's race also gets prize money.
