Fig Tree Flat, also called Willow Tree Flat, is located within Royal National Park, beyond Audley, hosting the Sri Chinmoy Sydney Series – Royal National Park Trail Runs. This event marks the Series finale and offers a practical trail running day. Participants should park near the start/finish, handle the national park vehicle entry fee, and prepare for running on dirt paths beneath the trees.
The races feature marked trail courses through forested areas of the park. The primary appeal lies in the park's terrain: shaded paths, varied surfaces, and sufficient trail complexity to maintain runner engagement. Wave starts are employed to manage participant flow, and a shuttle service operates from Loftus Station for those not arriving by car. A notable detail is the entry process: online registration concludes at 5pm the day prior to each race, with on-site entries available at the venue for an increased cost.
