The Tour de France is the greatest endurance sporting event in the world — three weeks every July where the best cyclists on earth cover 3,500 kilometres across French roads, mountains and iconic climbs that have defined the sport since 1903. The mountain stages in the Alps and Pyrenees are free to watch from the roadside, with hundreds of thousands of fans camping overnight to claim their spot on legendary cols like Alpe d'Huez and the Col du Tourmalet.
Three weeks across France. The mountain stages in the Alps and Pyrenees are the most spectacular — camp roadside for free. The Paris finale on the Champs-Elysées is one of sport's great images.
