The Tommyknocker Ultras is a one-of-a-kind 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 Mine Shaft Half features a mountain of an out and back course.
If you run one race this year, make it Tommyknocker. The Tommyknocker 12-hour event is part race, part carnival and ALL fun. Set in the foothills near Golden, the course is designed by you (in a lottery-style drawing) in a series of loops. The key question is: Which loops will you run during your 12 hour jaunt? And will you have more fun running or playing at the aid station? Come find out.
