The Hawaii Ironman Triathlon is the oldest, longest and most prestigious thriathlon in the world. It has its origin in 1978 when John Collins, a competitor of a Hawaii running race proposed combining three existing races together in order to know who is more fit (swimmers, runners or other athletes). These three competitions were the Waikiki Roughwater Swim (2.4 miles), the Around-Oahu Bike Race (112 miles) and the Honolulu Marathon (26.2 miles) and should be completed in succession. The winner will be called the Ironman. The first editions were at Waikiki, but from 1981 on the site changed to Kona, on the Big Island of Hawaii, the Saturday closest to the full moon in October. To get there, one must have finished in the top 10 the year before, or have qualified at a different race during the year.
El Hawaii Ironman Triathlon es el más antiguo, largo y prestigioso triathlon del mundo. Tiene su origen en 1978, cuando John Collins, un participante en una carrera en Hawaii propuso combinar tres competiciones ya existentes para saber qué atletas eran mejores (nadadores, corredores u otros deportistas). Las competiciones eran la Waikiki Roughwater Swim de natación (2.4 millas / 4 km), la Around-Oahu Bike Race de ciclismo (112 millas / 180 km) y el Marathon de Honolulu (26.2 millas / 42 km 195 m) y deberían hacerse las tres seguidas. El ganador sería considerado el "Ironman" (hombre de hierro). Las primeras ediciones eran en Waikiki, pero en 1981 la sede se trasladó a Kona, en la Isla Grande de Hawaii. La fecha es el sábado de octubre más cercano a luna llena.
