Professional cycling tours are organized events where cyclists compete over a series of stages, often spanning several days or weeks. These tours typically take place on public roads and can include various terrains, such as mountains, flat roads, and time trials. Notable examples include the Tour de France, Giro d'Italia, and Vuelta a España, which attract top cyclists from around the world. Participants in professional cycling tours race individually or as part of teams, aiming to complete the course in the shortest time. Each stage has its own challenges, and cyclists earn points and time bonuses based on their performance. The overall winner is determined by the lowest cumulative time across all stages.
