How to Watch the 2025 Men’s IRONMAN World Championship in Nice

On February 18, 1978, 15 competitors came to the shores of Waikiki, Hawai`i to take on the first-ever IRONMAN® triathlon. It was an idea hatched by John Collins, a Naval Officer stationed in Hawai`i, and his wife Judy during a swim club gathering. Collins' proposal was a friendly test of fitness combining the three toughest endurance races on Oahu into one race: The 2.4-mile Waikiki Rough-water Swim, the 112-mile Around-Oahu Bike Race, followed by a 26.2-mile run on the Honolulu Marathon course. That first race would set the stage for what IRONMAN triathlon would become: the most-challenging single-day sporting event in the world, and a brand symbolizing the belief that "ANYTHING IS POSSIBLE®.” Since its inception in 1978 on the Island of O`ahu and continued history in Kona on the Island of Hawai`i with recent stops in St. George, Utah and Nice, France, the IRONMAN World Championship® triathlon has etched its name in history through historic performances, inspiring athletes, and a lifetime of memories that define the sport of triathlon today. The IRONMAN World Championship remains the most iconic single-day endurance sporting event in the world and is the culmination of 40 global IRONMAN events with over 94,000 athletes around the world striving for one of the coveted qualifying slots of any sporting event in the world.
