12.5 miles
The course utilizes the trail system at Pine Valley Ski Area, featuring wide, mowed trails that wind through scenic mixed forests of pines and hardwoods. The 5.5K option follows established ski trails, while the 12.5-mile 'mystery distance' incorporates both trail sections and off-trail segments. Runners should expect some uncertainty in exact distances, as the race embraces its 'lost' theme. The terrain is described as suitable for runners of all levels, suggesting moderate difficulty without significant technical challenges.
