Road racing is a competitive sport where participants race on paved roads, often in organized events. These races can vary in distance, from short sprints to long endurance events, and can include various types of vehicles, such as bicycles, motorcycles, and cars. Road racing is popular worldwide and often features professional and amateur athletes. Events are typically held on closed courses or public roads that are temporarily closed to traffic. Road racing requires skill, strategy, and physical endurance, as racers must navigate turns, hills, and varying weather conditions. Major road racing events include the Tour de France for cycling and the Boston Marathon for running.
