Tiadaghton Trail Challenge - Waterville, PA

The Tiadaghton Trail Challenge is a trail running event held in Tiadaghton State Forest in the Pine Creek Valley near Waterville, Pennsylvania. The event offers two distance options:

  • Half Marathon
  • 10K

Both courses follow natural single-track and old road grades, and include technical, rocky and moss-covered tread, sustained climbs and steep descents, stream crossings, and scenic views such as vistas, hemlock and oak forest stands, trout streams, and small cascading waterfalls. Aid stations are provided and described as fully stocked with typical trail fuel. Awards are presented to the first male and female overall finishers, and pre-registered participants receive event swag.

The 10K is a loop that begins and ends at the Tiadaghton State Forest Resource Management Center and follows sections of PA-44, the Pine Creek Rail Trail, the Old Wagon Road, the Gleason Trail and the Tiadaghton Trail. The half marathon follows much of the 10K route but adds an additional loop to the highest point of Huntley Mountain, includes the Eiger Trail with about a 1,000 foot climb, the Log Slide Trail, the Wolf Path climb of roughly 800 feet, and finishes via Middle Hill Trail back to the DCNR building.

Event rules state there are no refunds, no deferrals, no bib transfers, no bandits, and no same-day registration. Registration closes Sat, Oct 31 at 11:59 PM ET. All proceeds benefit the Kasey Jack Kemmerer Memorial Scholarship Fund for Jersey Shore Area High School graduates. Visit the organization's website for the most recent information.
