Tiadaghton Trail Challenge

The Tiadaghton Trail Challenge is a trail running event held in Tiadaghton State Forest near Waterville, PA. The event offers two distances and uses singletrack, old logging grades, gravel roads, and sections of the Pine Creek Rail Trail. Terrain includes rocky and moss-covered trails, steep climbs and descents, shale outcrops, hemlock and oak forest, trout streams, and small cascading waterfalls. Aid stations will be fully stocked.

Course options:

  • Half Marathon
  • 10K

The 10K is a loop beginning and ending at the Tiadaghton State Forest Resource Management Center. It follows PA-44 briefly, the Pine Creek Rail Trail, the Old Wagon Road, the Gleason Trail to the Tiadaghton Trail, and returns via singletrack and the rail trail parking area.

The Half Marathon follows the 10K route with additional loops and connecting trails. It includes a new two mile loop to a high point on Huntley Mountain, the steep Eiger Trail climb with roughly 1,000 feet of ascent, the Log Slide Trail descent, a final ascent on Wolf Path with an 800 foot climb, and a technical dried stream bed section before returning on Middle Hill Trail.

Awards are given to the first male and first female overall. Pre-registered entrants receive event swag and there is a post-race food celebration. All proceeds benefit a memorial scholarship fund that supports at least one graduating senior from Jersey Shore Area High School each year. Registration rules include no refunds, no deferrals, no bib transfers, no bandits, and no same day registration. Registration closes October 31 at 11:59 PM ET.
