Event Description

The Tommyknocker 12-Hour is a one-of-a-kind challenging 12-Hour timed event, designed by YOU… and tiny colorful balls. Gazing out at the spectacular views of Colorado’s Front Range above the Denver Metro Area, this race will make you laugh, and possibly cry. The course features double-track and single-track trails with ZERO pavement, and an aid station you’ll want to hang around at for hours (we’re that much fun)!

The Mine Shaft Half features a mountain of a lollipop loop course, quite literally. Enjoy the aggressive elevation gain, we promise you won’t feel shafted. We guarantee we will have the best and goofiest aid station you’ve ever experienced in a half marathon. The Mine Shaft Half is the most challenging half marathon in Colorado’s Front Range.

Choose your fate at the Tommyknocker 12-hour event, and remember fate is not always on your side. Sometimes fate has a different plan in store for you. Facing the unknown, and dreading the pastel ping pong balls is part race, part carnival, and ALL fun. Time will take away the unknown and will abate the fear. You will be left with joy, pride, and confidence in your running soul. Face #Adversity, face the unknown, and come to know yourself better through it all.
