An Ironman race is a long-distance triathlon that consists of three main segments: a 2.4-mile (3.86 km) swim, a 112-mile (180.25 km) bike ride, and a 26.2-mile (42.20 km) marathon run. Athletes must complete the entire race within a specific time limit, typically 17 hours, to earn the title of Ironman. These races are held in various locations around the world and attract both professional and amateur athletes. Participants train extensively to build endurance and strength, as the Ironman is known for its challenging nature and requires a high level of physical fitness.
