The winner of the race is the first rider to cross the finish line. However many riders are grouped together in teams. Teams usually have commercial sponsors and are named after the main sponsor. For example some famous teams have been called T-Mobile, Rabobank, ONCE, and Lampre. There can be up to twelve team members in professional races. Team riders decide which team member has the best chance of winning the race. The choice will depend on how hilly the route is, the chance that everyone will finish together in a sprint, and other things. The rest of the team will work to help him or her win the race.
