Tommyknocker Ultramarathons 12-Hour

September 6, 2017

White Ranch Open Space, Golden, CO

The Tommyknocker Ultras is a challenging 12-Hour timed event with spectacular views of Colorado’s Front Range above the Denver Metro Area. 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.
