Slate Run Trail Race
A trail event in Slate Run, Pennsylvania, held in the remote, rugged mountains of Tiadaghton State Forest. The course goes through the Algerine Wild Area and the Red Run sections of the Black Forest Trail, featuring technical single track, stream crossings, and elevated views.
- 25K
- Half Marathon
Both distances share the same trail for the first nine miles. At the Manor Fork camps, half marathon runners follow the road to the last aid station and then onto the finish. 25K runners continue along the streambed and climb Old Supply Trail. There is a cut-off for the nine mile section at 12 noon; after that time all participants will be directed onto the half course. Half runners must reach the Manor Camp intersection by 1pm or they will be removed from the course. Organizers report that in 2025 all entrants made the 1pm cut-off.
Registration opens December 16, 2026 at 8:00 PM ET via UltraSignup. The field is limited to the first 225 runners or until May 20, whichever occurs first. The event policy states there are no refunds, no deferrals, no switches, and no bandits. The event is organized by PA Trail Dogs and listed for Slate Run, PA with a local venue address of 153 Yoder Lane. Visit the organization's website for the most recent information.
