The Tour de France is the world’s most famous cycling race, held annually over three weeks in July. First organized in 1903, the race covers around 3,500 kilometers (2,200 miles) through France and sometimes neighboring countries, featuring a mix of flat stages, mountain climbs in the Alps and Pyrenees, and time trials. Cyclists compete for the prestigious yellow jersey (maillot jaune), awarded to the overall leader. Known for its grueling challenges and breathtaking scenery, the Tour draws millions of spectators along the route and millions more watching worldwide, making it a cornerstone of international sports and French culture.
