Event Details
Course Description
The race kicks off with a single 400 m lap in the sheltered waters of Obelisk Beach, offering calm conditions for all skill levels. Cyclists then tackle five laps of Chowder Bay Road, a smooth coastal road with gentle undulations and stunning harbour views. The run consists of two laps weaving through historic Middle Head Barracks and the leafy bush tracks of Middle Head Reserve, providing a mix of road and trail footing. The closed‑course format ensures a safe, traffic‑free experience, while the varied scenery keeps participants motivated from start to finish.
