The Glenbrook Marathon returns to the Euroka Clearing of Blue Mountains National Park on October 19, 2025, offering a mix of distance options—25 km, 34 km, and the full 42.2 km marathon—suited for trail runners seeking both challenge and beauty. Organized by Running Wild NSW, the race features a mix of technical singletrack, fire trails, steep climbs, and fast descents. Participants pass highlights like Mount Portal, Red Hands Cave, and Camp Fire Creek, weaving through eucalyptus forests and heritage-listed terrain. With a 6-hour cutoff, gear requirements (minimum 500 ml water), and a self-supported ethos, the event appeals to experienced trail athletes and adventurous marathoners alike. The course’s mix of cultural landmarks and dramatic bushland offers one of the most immersive trail experiences in New South Wales.
