Heavy Half, Marathon, & 55K Trail Runs
Kick off this fall with one of our ambitious trail races at our weekend-long Mountain RATS celebration! We offer 3 different trail runs to let racers of different levels push their stamina and training to the limit: a heavy half marathon, a full marathon, and a 55K. Each course follows a system of similar trails in the gorgeous area of Eagle, Colorado. You’ll race along rugged, singletrack mountain trails while taking in all of the stunning outdoor beauty of this remote location. Racers will climb between 2,720’ to 6,400’ on courses that will be challenging, beautiful, and almost 100% dirt.
After the trail runs are done, all racers, families, and friends are welcome to relax at our after-party featuring live music, food and drinks, massages, and more. Reserve your spot in our heavy half marathon, full marathon, or 55K today!
