Sydney Trail Half Marathon : Summer Edition
The Sydney Trail Half Marathon is a trail race held at Lake Parramatta Reserve on Saturday 12 and Sunday 13 December 2026. The event uses a single-lap course of 21 km with approximately +367 m / -367 m elevation, and a strict 4 hour cutoff for the half marathon.
The route blends technical single-track sections and wider fire trails, and passes a waterfall, lakeside viewpoints, and eucalypt canopy. There are multiple road crossings on the route with marshals to assist. The course is marked and a GPX link is provided for navigation.
Aid support includes a single on-course aid station located at the 9.5 km and 14.5 km marks, plus an aid station at the finish. On-course nutrition includes Näak Ultra Energy Drink Mix and products from PURE Sports Nutrition; aid stations supply water, fruit and lollies. The event is cupless: athletes must carry their own cup, bottle or hydration system.
Mandatory gear to be carried at all times includes a fully charged mobile phone with live SIM, one compression bandage, and water-carrying capacity of 500 ml. Parking is available outside the lake and on surrounding streets; no parking is permitted inside the lake. Facilities near the start include a cafe and restrooms.
Race capacity is limited to 450 runners per day. Race-day bib collection is from the Race Hub; bibs are not posted out. Post-race items include a finishers medal, race singlet, a commemorative bucket hat, free race photos and a post-race BBQ. A bag-drop gazebo is provided.
