Fun Fact:
The Ironman Triathlon is that it originated from a challenge between a group of Navy SEALs and endurance athletes back in 1978. The first Ironman event took place on the Hawaiian island of Oahu, combining three existing long-distance races: the Waikiki Roughwater Swim (2.4 miles), the Around-Oahu Bike Race (112 miles), and the Honolulu Marathon (26.2 miles).
