Rocky Mountain Flyathlon


The Flyathlon is a multi-sport event that integrates three activities that are surging in popularity; trailrunning, fly fishing, and craft beer. While many enjoy these activities independently, we have found over the years that putting them together is even more enjoyable. Simply put, many of the best and most beautiful places to fish are way back in the woods, and the quickest way to get back to these remote places to maximize fishing time is to trail run. And once you have run back from that mountain lake or stream (or while you are there…), all of that effort is rewarded with high quality, local craft beer.
