Organiser's 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). Were 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 youre allowed on these trails without a court date.

Its technical, its rugged, and nature will likely try to trip you. But hey, well 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!
