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.

Not up for 12-Hours? Join us for the Mine Shaft Half!

Event Start Location
White Ranch Lower Lot
Glencoe Valley Road
Golden, CO

Course Description
After running from the race’s start location to the upper White Ranch Parking Lot, runners will dive their fists into a bucket full of colored balls. These colored balls will be colored Red, Green, Orange, and Yellow. The color the runner pulls will indicate which loop they will now run.

Each loop will be marked with flagging tape the same color as the ball pulled (Green Ball follows Green Markings, Red Ball follows Red Markings, etc). After completing the selected loop, their miles will be recorded, and a new ball will be selected by the runner. This repeats for nearly 12 hours.

No two runners will run the same exact course. It’s the luck of the draw and how tenacious one can be in order to run as many miles as they can in this 12-Hour Carnival. Runners are guaranteed 14.5 miles totaled on the approach to the upper lot and the return run back to the bottom at the end of the race. Runners MUST return to the bottom lot prior to the 12-hour cut-off in order for their miles to count. Late runners will receive a ZERO for the event.

Unique Finishers awards for all runners. No age group or 1-3rd awards given. Enjoy a community celebratory race!
