Event Maps
The Marathon is 6 laps around our course. 2500 feet of vertical gain on the singletrack terrain will challenge all abilities. With the course configuration, you will pass through the full aid station 5 times.
The half-marathon is three laps around the course. With 1250'+ of vertical gain, it will be a challenging half-marathon but also a nice early-season challenge for a trail runner.
The 10k race starts with the "prologue" section of the course, effectively creating a 1.5 lap circuit. 550'+ of vertical features a few kicker climbs keeping the challenge for everyone.
The 5k is two laps of the "prologue" course. This run is fast, but the 270' of vertical includes two summits of the prologue kicker climb, keeping it a true trail run.
Event Description
Fifth Street Rock Monster
The Technical Tango
Sunday, April 12, 2026
Forever Farm | Mertztown, PA
Welcome to the Fifth Street Rock Monster (formerly known as Rockland Rad Run, before the lawyers got involved). We’re throwing a spring awakening at Forever Farm. A slice of private singletrack heaven normally guarded by gates and "No Trespassing" signs. This is the only weekend of the year you’re allowed on these trails without a court date.
It’s technical, it’s rugged, and nature will likely try to trip you. But hey, we’ll have a beer waiting at the end.
The Details (Pay Attention)
The Vibe: High-energy singletrack, questionable jokes, fly tunes, and fresh food.
The Course: We fixed it. No more confusing "figure 8." Continuous loops. Simpler navigation. Same suffering.
The Distances: 5K, 10K, Half Marathon, Full Marathon.
The "Two-Headed" Relay: Teams of three. Two runners on course at the same time. This isn't a solo sufferfest. It's a squad mission. MONEY IS ON THE LINE!
