Gnar Runners

Horsetooth RockGnar Runners events are designed to promote enthusiasm and passion for the sport of mountain, trail and ultrarunning in and around the beautiful mountains of Northern Colorado. 

Whether you are leading the charge at the front of the field, playing host in the middle of the pack or chasing course cut-offs, our dirt-based races are geared towards helping you achieve your off-road running goals in stunning outdoor environments.

While we seek to create challenging courses on as much gnar-filled terrain as we can reasonably find, we also guarantee impeccably marked courses, bountiful aid stations and a post-race atmosphere to remember.

Be gnarful out there!
