The Experience

The Fifth Street Rock Monster is a rare beast: a trail race on private singletrack at Forever Farm, normally off-limits without a court date. This is the only weekend of the year runners are welcome to tackle its rugged, technical loops. The course demands attention—roots, rocks, and tight turns keep you honest—but the reward is a cold beer at the finish and the satisfaction of conquering a hidden gem.

The vibe is high-energy and irreverent, with questionable jokes, live tunes, and fresh food fueling the after-party. Free camping on Saturday night turns the event into a weekend community gathering. Distances range from 5K to 100K, including a unique "Two-Headed" relay where teams of three have two runners on course simultaneously—with money on the line. With a typical winning half-marathon time around 1:57, the field is competitive but welcoming.

The course consists of continuous loops, making navigation simple so you can focus on the terrain. It's a true trail runner's haven—underrated, wild, and full of character. If you crave singletrack that feels like a secret, this is your race.
