About This Race

The Tussey Mountainback stands as one of Pennsylvania's premier autumn ultra events, weaving through the pristine landscapes of Rothrock State Forest. This 26-year-old race combines the solitude of solo ultra running with the camaraderie of relay competition, offering both individual 50-mile and 50K challenges alongside team relay options. The course showcases central Pennsylvania's diverse terrain, from shaded forest roads to open vistas, connecting several state parks and natural areas in a single challenging loop. What sets Tussey Mountainback apart is its commitment to environmental stewardship and community spirit. The race operates under strict guidelines to preserve the forest ecosystem while maintaining access to these public lands. With nearly three decades of history, the event has cultivated a loyal following among both recreational and competitive runners who return year after year for its unique blend of challenge and scenery. The October timing captures Pennsylvania's peak fall foliage, making this as much a visual feast as a physical test.

The 50-mile loop course winds through Rothrock State Forest on predominantly unpaved roads (82% dirt, 18% paved), taking runners through varied terrain that includes significant climbs, rolling sections, and rewarding descents. The route connects Whipple Dam State Park, Alan Seeger Natural Area, Penn-Roosevelt State Park, Colyer Lake, and Bear Meadows Natural Area, offering a tour of central Pennsylvania's most scenic protected lands.

Runners encounter both shaded forest segments and open areas with overlook vistas, with the course featuring a mix of uphill, level, and downhill grades throughout. The terrain is non-technical but demanding, with the 5,485 feet of elevation gain distributed across rolling hills and sustained climbs that test endurance without requiring technical trail skills.
