History: Tour De France

The Tour de France is a bicycle race known around the world. It typically has 21 days, or stages, of racing and covers more than 3,200 kilometres (2,000 mi). The shortest Tour was in 1904 at 2,420 kilometres (1,500 mi), the longest in 1926 at 5,745 kilometres (3,570 mi). The three weeks usually include two rest days, sometimes used to transport riders from a finish in one town to the start in another. The race alternates between clockwise and anticlockwise circuits of France. The first anticlockwise circuit was in 1913. The New York Times said the "Tour de France is arguably the most physiologically demanding of athletic events." The effort was compared to "running a marathon several days a week for nearly three weeks", while the total elevation of the climbs was compared to "climbing three Everests."
The number of teams usually varies between 20 to 22, with nine riders in each. Entry is by invitation to teams chosen by the race organiser, the Amaury Sport Organisation. Team members help each other and are followed by managers and mechanics in cars.
