Course details

The full traverse is about 25 miles each way with approximately 7,500 feet of climbing each direction. The 25K option includes about 4,000 feet of climbing along the ridge. The course is largely unmarked, though signage exists along the trail. Participants are required to download the GPS track to a phone or watch and study maps; maps are provided at bib pickup. The 50 miler uses South Pond as start and finish with a turnaround aid station at Jefferson Inn. The 25 miler starts near Jefferson Inn after bussing from South Pond and returns to South Pond. The 25K starts from the Berlin Fish Hatchery by bus and finishes at South Pond.
