Quad Rock 25 & 50 Mile Trail Races
Runners love the Quad Rock 50 for its honest Front Range mountain terrain—long stretches of embedded rock, boulder fields, and steep ridgelines through Poudre Canyon and Roosevelt National Forest that reward perseverance with sweeping views of pine forests, the Poudre River, and distant snow‑capped peaks. The race’s over‑10,000‑ft of gain is no gimmick, and the event’s well‑marked course, helpful volunteers, and solid aid stations (Tailwind, hot soup, pretzels) create a community‑focused, high‑quality ultra experience. However, the relentless rockiness can be punishing for newcomers, the remote location means limited cell service and almost no spectators, and the start is just a basic trailhead lot with no expo—making it best suited for trail‑seasoned runners looking for a serious tune‑up.
