The event is described as the 5th annual running of the race. Start and finish are at the Tiadaghton State Forest Resource Management Center. Aid stations will be fully stocked. Awards are given to the first male and first female overall. The organizer does not allow refunds, deferrals, bib transfers, unregistered participants, or same-day registration. Pre-registered entrants receive event swag.
Course and proceeds
Both courses run on technical, rocky, moss-covered singletrack with steep climbs and descents. Scenery includes vistas, hemlock and oak forest, trout streams, and small waterfalls. The 10K is a loop that uses the Pine Creek Rail Trail, the Old Wagon Road, the Gleason Trail (about 0.75 miles and steep), and sections of the Tiadaghton Trail before returning to the rail trail and the resource center.
The half marathon follows much of the 10K route but adds a new roughly 2-mile loop to reach the highest point of Huntley Mountain, a ~1,000 ft climb on the Eiger Trail, the Log Slide Trail descent, and the Wolf Path ascent of about 800 ft. All proceeds benefit a memorial scholarship fund that awards at least one graduating senior from the local high school each year. Visit the organization's website for the most recent information.
