Australia's oldest triathlon
More than four decades on, the Nepean Triathlon still draws elite athletes, age groupers, first-timers, and the loyalists who wouldn’t miss it for the world. It’s not just a race — it’s a fixture. A ritual. A piece of Australian sporting history that keeps writing itself every November.
Over recent years, we’ve grown the event into the Redline Games Festival – expanding the race distances so more athletes than ever can be part of this epic weekend.
Whether it’s your first triathlon or your 44th Nepean Tri, there’s a distance for you.
This year, be part of it.
