Born from the ranks of the Fort Collins trail running community, Gnar Runners events are designed to promote enthusiasm and passion for the sport of mountain, trail and ultra running. 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 running lines on as much gnar-filled terrain as we can reasonably find, we also guarantee impeccably marked and measured courses, bountiful aid stations, and a post-race atmosphere to remember.
