Forever Farm | Mertztown, PA
Welcome to the Fifth Street Rock Monster. 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 Vibe: High-energy singletrack, questionable jokes, fly tunes, and fresh food.
The Course: Continuous loops. Simple navigation. Same suffering.
The Distances: 5K, 10K, Half Marathon, Full Marathon, Ultra Rock Relay (100k cumulative distance)
The "Ultra Rock" Relay: Teams of three. Two runners on course at the same time. 100k cumulative distance. This isn't a solo sufferfest. It's a squad mission. MONEY IS ON THE LINE!
Learn More About the Ultra Rock RelaySaturday, April 10: Rock Monster MTB races (9am-3pm). Heckle cyclists. Scout lines. Join the party.
Camping: FREE camping Saturday night at Forever Farm. Camping is boondocking - no electric or water hookups. Generators must be off by 10pm (no overnight gas generators permitted). Survive the pre-race campfire hydration, and you're golden.

Beer: Bright Path Brewing beers available on site! All runners (21+) get one complimentary beer post-race. Additional cans are $5, and 6-packs are available to go.
Overall: Top 3 Overall/F/NB in each solo distance win awards. Per our Fifth Street protocols, we award an OVERALL podium, not just the men's podium. Fast ladies can get recognized twice - once on the overall and again on the women's podium. Non-binary individuals are eligible for the Overall podium or the women's podium if that is how they have pre-registered. If we have 10 or more non-binary participants who identify as competing equally against each other, we can host an NB podium.

Finisher Award: Medals for those who make it to the finish line!
