Hounslow Classic
Blackheath, Australia • 11-13 Sep 2026
The Hounslow Classic is a weekend of gnarly and spectacular trail racing held in Blackheath, within the Grose Valley Wilderness of the Blue Mountains. Races include the Hounslow Marathon (42k) and the Hounslow 17k, with the option to enter both in the Hounslow Monster Stage race. The Blue Mountains skyrace is known for brutal climbs, steep technical terrain, and jaw‑dropping valleys, as runners traverse cliff tops, canyon trails, and ancient landscapes, climbing rocky peaks for 360-degree views of the Grose Valley. Key features include the Grand Canyon loop for the 17k and the marathon’s out‑and‑back to the Pinnacles via Perrys Lookdown and Lockleys Pylon. The event honors Ngurra Country of the Dharug and Gundungurra peoples. Visit the organization's website for the most recent information.
