Busselton Festival of Triathlon

The Busselton Festival of Triathlon is Western Australia’s iconic multisport weekend held in Busselton, on the shore of Geographe Bay. The festival features the Busselton 100 long course (2 km swim in front of the Jetty, 80 km bike through Ludlow Tuart Forest, and an 18 km run along the bay), the shorter Foreshore Sprint, a Busselton Aquabike, and a Kids Triathlon at Barnard Park. The event attracts thousands—over 2,300 participants—driven by a friendly, festival atmosphere that includes an expo, food trucks, and a dedicated app.

It’s a community-focused, family-friendly celebration of swim, bike, run. The 2026 edition marks 25 years of the festival. Visit the organization's website for the most recent information.
