Course and logistics

All courses start and finish at the main Squak Mountain trailhead and begin with a steady climb. There are three loop options: a 12K loop, a half-marathon loop, and a 50K loop; the 50K includes extra loops and is roughly two loops of the 50K route. Summit points include the southeast and west peaks of Squak. Published elevation gain is approximately 1800' for 12K, 3400' for the half marathon, and 8300' for 50K. Aid stations are placed along the courses (examples: 12K at 3.4 miles; half and 50K at multiple locations up to 26.0 miles). The event is cupless - participants must carry a refillable container. Trails remain open to other users, including hikers and equestrians, and parking at the trailhead is limited. Visit the organization's website for the most recent information.
