Ultra cycling is a form of long-distance cycling that involves riding for extended periods, often exceeding 100 miles in a single event. Participants may compete in races or ride for personal challenges, covering distances that can reach several hundred miles in a day. Events can vary in format, including time trials, point-to-point races, or multi-day challenges. Ultra cyclists often train rigorously to build endurance and stamina, and they must manage nutrition and hydration carefully during their rides to maintain performance over long distances.
