The Nepean Triathlon remains an iconic sporting and community event on the Aussie triathlon calendar. The event and the history it has created is a testament to all the volunteers, sponsors, race organisers and entrants who have supported what is now Australia’s oldest triathlon.
In 1982, a couple of mates, after seeing the Hawaiian Ironman on TV, decided to stage their own triathlon at the foot of the Blue Mountains. The Nepean Triathlon emerged and has attracted elite athletes worldwide, age group combatants, first-timers, and some who complete it as an annual ritual.
In 2023, Mark “Emo” Emerton and Elite Energy rescued and reinvented Australia’s Oldest Triathlon, setting the stage for many more exhilarating years of the Nepean Triathlon. The future is looking brighter and more vibrant than ever!
