Event Details
Course Description
The race kicks off with a 1.9 km rolling swim in the calm waters of Geographe Bay, staying close to the Busselton foreshore for sheltered conditions. Athletes then transition to a 90 km flat bike ride that follows the coastal road, offering uninterrupted sea views and minimal elevation change. The final 21.1 km run is equally flat, winding along the picturesque Signal Park and beachfront promenade, making pacing straightforward and ideal for a fast finish. With supportive crowds and a relaxed vibe, the course is designed for fast times and a memorable race day experience.
