Obstacle Course Race / Mud Run Venues in Colorado

Mud, walls, ropes and a lot of laughing: this page lists Colorado venues that host obstacle course races and mud runs. Many events take place at ski areas, ranches, fairgrounds and open-space parks where organizers can build courses across hills and trails.

Most races run from late spring through early fall, when trails dry out and water obstacles are bearable. Formats range from short, family-friendly mud runs and kids courses to longer, competitive races with mandatory obstacles and age group awards. High elevation adds a challenge, so pace yourself, hydrate and expect cooler mornings in the mountains.

Use this directory to find upcoming races and learn about each location. Teams and charity groups often run together, so these events work well for group fundraising. Organizing a race, a youth mud run or a training clinic? Feel free to submit it to Colorado Under Par at no cost.
