Slate Run Trail Race : June 5, 2027
Slate Run Trail Race is a trail running event in Slate Run, PA, organized by PA Trail Dogs. The event offers two distance options:
- 25K
- Half Marathon
The course runs through the remote mountains of Tiadaghton State Forest. Runners follow sections of the Black Forest Trail that pass through the Algerine Wild Area and the Red Run area. The route includes technical single track, multiple stream crossings, and scenic vistas.
Both distances share the same trail for the first nine miles. At the Manor Fork camps the half marathon course turns onto the road toward the final aid station and the finish. 25K runners continue on the trail along the streambed and then ascend Old Supply Trail. The cut-off for the nine mile section is 12 noon; after that time all participants will be directed onto the half marathon course. Half marathon runners must pass the Manor Camp intersection by 1 pm or they will be removed from the course. In 2025 all participants met the 1 pm cut-off.
Registration opens December 16, 2026 via UltraSignup. The field is limited to the first 225 runners or until May 20, whichever comes first. The event policies state no refunds, no deferrals, no switches, and no bandits. Visit the organization's website for the most recent information.
