The Hounslow Classic is renowned for its challenging courses and spectacular scenery. The 17 km race on Sunday, September 14, takes runners through the scenic cliff-top trail between Govetts Leap and Evans Lookout, traversing the ancient Grand Canyon track with an elevation gain of 900 meters. The 43 km marathon on Saturday, September 13, offers a grueling 2,500-meter ascent, leading participants through the Grand Canyon, Perrys Lookdown, and Lockleys Pylon, culminating at the Pinnacles Car Park. For the youngest enthusiasts, a 1.5 km kids’ race provides a fun introduction to trail running. All races start and finish at Allview Escape in Blackheath, offering a festival-like atmosphere with vendors and live results.
