On The Rocks Trail Runs
On The Rocks Trail Runs takes place on June 27, 2026 at Rocky Ridge County Park in York, PA. The event offers multiple trail distances on a looped route that mixes rocky sections, dirt, and tree roots.
Distances offered:
- 50K three loops of the 16.7K course
- 33.3K two loops of the 16.7K course

The route features rolling hills and rocky terrain. Each full loop contains four and a half climbs that average approximately 250 vertical feet each, making one loop about 1,350 feet of elevation gain. The 16.7K is one loop of the course; longer distances repeat that loop as noted above.
