The 5th Annual Tommyknocker Ultras will take place on May 19, 2018 The Tommyknocker Ultras is a challenging 12-Hour timed event with spectacular views of Colorado’s Front Range above the Denver Metro Area. We're also offering a half marathon for those looking to enjoy the camaraderie with us! The course features double-track and single-track trails with 0.0% pavement.
The Tommyknocker course was designed to challenge you by running multiple loops without knowing the loop you’ll run next. It’s more of a 12-hour brain cramp with some running thrown in. Runners will enjoy our “carnival-like” setting.
