A Half Ironman is a long-distance triathlon that consists of three segments: a 1.2-mile (1.9 km) swim, a 56-mile (90 km) bike ride, and a 13.1-mile (21.1 km) run. It is half the distance of a full Ironman, making it a popular choice for athletes looking to challenge themselves without committing to the full distance. Participants typically train for several months to build endurance and improve their performance across all three disciplines. Half Ironman events are held worldwide and attract both amateur and professional athletes, offering a competitive yet supportive environment for all levels of fitness.
