Event Overview
The 3 Valleys Runningworks Marathon returns on Sunday, 6 September 2026, for its sixth year, based at the Bickley Outdoor Recreation Camp in Perth’s Bickley Valley, Western Australia. The 2026 edition introduces a new and updated marathon course that includes additional singletrack and a Victoria Dam lookout section. Distances include 10km, half marathon, marathon, and a team relay. Scheduled start times are 7:00am for the marathon and relay, and 7:30am for the half and 10km.
What the Course Demands
This is described as a technical trail run with substantial singletrack, major climbs, and steep descents, so athletes should expect frequent changes in effort and footing. The updated marathon course adds more singletrail and incorporates the Victoria Dam lookout, with the “Quad Cruncher” climb highlighted as one of the toughest sections. A 7.5-hour cut-off applies across events, placing emphasis on steady pacing and efficient transitions through more demanding segments.
Who This Event Suits Best
This event suits runners who enjoy technical trail challenges and are comfortable managing sustained climbs and descents over longer durations. The 10km provides an entry point for those new to more technical courses, while the half marathon and marathon suit experienced trail runners seeking a tougher profile and varied terrain. The team relay option can work well for athletes wanting the event atmosphere without completing the full marathon distance solo.
