The Tour de France is the biggest race in professional cycling, three weeks of mountain passes, time trials, and tactical pressure watched by millions along French roadsides and around the world.
The Tour de France is a three-week men's stage race held each July across France and occasionally neighboring countries. It is the most-watched annual sporting event in the world and the centerpiece of the professional road racing calendar.
First held in 1903, the Tour was created to sell newspapers and has since become the defining event of the sport.
The Tour matters because it draws the strongest field, the deepest team rosters, and the widest range of terrain in professional cycling. Every stage type appears across three weeks: mountain-top finishes in the Alps and Pyrenees, flat sprints, time trials, and wind-exposed valley roads. The yellow jersey changes hands through crashes, breakdowns, tactical miscalculation, and raw climbing power. Even stages that look quiet on paper create tension around positioning, time gaps, and team control.
The Tour is won in the mountains and the time trial, but lost anywhere. The route changes each year but follows a stable pattern: a nervous opening week with flat stages and short climbs that reward positioning and power, a second week that introduces serious mountain stages in either the Pyrenees or Alps, and a final week that includes the hardest summit finishes and a concluding time trial or ceremonial ride into Paris. Crashes, crosswinds, and splits in the opening week can eliminate contenders before the mountains arrive. The high mountains separate the overall contenders, but time gaps are often smaller than expected because teams control the pace. Time trials reward specialists and punish pure climbers. The race is usually decided across four or five key stages, with the rest serving as recovery, positioning, or opportunities for breakaway stage hunters.
