Course
The course runs in Montour Woods Conservation Area and Moon Park and is described as typical Western Pennsylvania trail terrain: twisty dirt singletrack with roots, switchbacks, and rocky sections. The route has three parts: Liftoff, Orbit, and Final Approach.
Liftoff is a 1.25 mile segment starting at Clearview Shelter in Moon Park that connects to Montour Woods, including a downhill section and a wooden boardwalk. Orbit is a 9 mile loop through Montour Woods that passes a reclaimed concrete clearing of an old Nike missile site, a powerline, Meeks Run with a waterfall and cave feature, and an old oil well. Aid stations are placed approximately every 3-4 miles on the loop. The Half Marathon uses one Orbit loop, the 20 Mile uses two loops, and the 50K uses three loops. Final Approach is a 2.87 mile mostly double-track loop around Moon Park for the Half Marathon and 50K; the 20 Mile finishes by returning on the 1.25 mile Liftoff segment in reverse.
