HalfIronman

A Half Ironman is a long-distance triathlon event. It is one of two standard distances offered by the World Triathlon Corporation (WTC), the other being the full Ironman distance. The Half Ironman distance consists of a 1.2-mile (1.9 km) swim, a 56-mile (90 km) bicycle ride, and a 13.1-mile (21.1 km) run. These distances are exactly half of those in a full Ironman triathlon.

The Half Ironman race is often referred to by various names depending on the race organizer. The WTC specifically owns the "Ironman" brand and uses "Ironman 70.3" for its branded events, with the number 70.3 referring to the total mileage of the race. However, many other triathlon organizations host races with the same half-Ironman distances but use different names, such as "Half Iron" or simply a triathlon with the specified swim, bike, and run distances.

These events are a significant challenge for athletes, requiring months of dedicated training to build the endurance and stamina needed to complete all three disciplines consecutively. Participants range from seasoned triathletes looking for a challenging race to ambitious amateurs testing their limits. Completing a Half Ironman is considered a major accomplishment in the endurance sports world. The popularity of these races has grown considerably, with numerous events held annually across the globe.
