An Ironman triathlon is a long-distance race that consists of three segments: swimming, cycling, and running. Participants start with a 2.4-mile (3.86 km) swim, followed by a 112-mile (180.25 km) bike ride, and finish with a 26.2-mile (42.20 km) marathon run. Athletes must complete the entire race within a specific time limit, usually 17 hours. Ironman events are held worldwide and are known for their challenging nature, attracting both amateur and professional athletes. Training for an Ironman requires significant dedication, as competitors must build endurance and strength across all three disciplines to successfully complete the race.
