In 1982, the Ironman Triathlon was still something of a niche event. That would change after images of Julie Moss were beamed around the world.
During the Ironman, athletes take on a 3,86 km swim, a 180,25 km bicycle ride, and then a cheeky 42,2 km marathon. The Enduroman takes things even further.
It takes an incredible amount of discipline, determination and drive to tackle an IRONMAN event. We spoke to triathlete Paul Hilliard about the challenges.
