Ironman World Championship 2017
Triathlon's most iconic event brings athletes together on the world stage.
The inaugural "Hawaiian IRON MAN Triathlon" was conceptualized in 1977 as a way to challenge athletes who had seen success at endurance swim, running and biathlon events. Honolulu-based Navy couple Judy and John Collins proposed combining the three toughest endurance races in Hawai'i - the 2.4-mile Waikiki Roughwater Swim, 112 miles of the Around-O'ahu Bike Race and the 26.2-mile Honolulu Marathon - into one event.
