Mountain Creek Mayhem

About the Event

The Mountain Creek Mayhem returns to Gardners, Pennsylvania on September 19th, offering a series of challenging trails through the northern Michaux State Forest.
This event takes place in Pine Grove Furnace State Park, where runners will encounter diverse terrain ranging from sandy boulder ridgelines and woodland savannahs to technical forest paths. The course conditions are firm but slightly soft underfoot, ideal for trail running enthusiasts seeking a mix of swift single-track sections and more challenging rooty trails. On race morning, expect temperatures in the mid-70s Fahrenheit with moderate UV index levels and low humidity.
Since its inception, Mountain Creek Mayhem has become an essential part of the local racing calendar, attracting runners from across Pennsylvania and beyond for its scenic routes through historic Michaux State Forest. The event supports conservation efforts within the park and promotes outdoor recreation in Gardners, fostering a sense of community among trail running enthusiasts.
The course begins at Pine Grove Furnace State Park's Fuller Lake Day Use Area, featuring rolling hills and varied elevation changes that challenge even seasoned runners. Aid stations are strategically placed along the route to provide essential hydration and nutrition options such as water, electrolyte drinks, fruit, potatoes, Fritos, cookies, gels, blocks, stroop waffles, candy, rice krispie treats, pickles, sometimes meatballs, and menstrual products for female participants.
Weather on race day is expected to be mild with temperatures ranging from the mid-60s to low 70s Fahrenheit in the morning hours climbing into the upper 70s by early afternoon. Skies should remain clear without any significant precipitation risk.
