Nepean Triathlon

The Nepean Triathlon is presented as Australia’s oldest triathlon and forms the core event of the Explore Worldwide Redline Games Festival. The race has been held since 1982 and is based at the Sydney International Regatta Centre, which has hosted the event since 1999. The program is set up to include elite athletes, competitive age groupers, first-time triathletes, team entries, and youth categories.

The festival offers multiple standard race formats and junior events across a weekend, with several established distances for different competitors:

  • Nepean: 1 km swim, 30 km bike, 8 km run
  • Classic: 2 km swim, 60 km bike, 16 km run
  • Sprint: 750 m swim, 20 km bike, 5 km run
  • Super Sprint: 200 m swim, 8 km bike, 2.5 km run
  • TriKidz categories with shorter swim, bike and run distances

An Aquabike option is offered for the Classic swim and ride without the run. The event highlights its long history, a Hall of Fame, and partnerships with local and national organisations. Organisers describe the weekend as expanded to allow more athletes to participate across the different distances and formats, while maintaining the Nepean distance as the original, iconic race within the festival.
