Due to the destructive floods of September 2013, and fragility of the Boulder Trail Network, this years Brass Knuckle Shuffle has been relocated. Trail closures are still numerous in Boulder and surrounding areas, some of which include trails traditionally used for this event. Out of respect for other trails newly reconstructed and the number of runners registered for the event we will be utilizing our "back-up" course in the Golden/Morrison/Lakewood Area. This secondary course offers 25 miles with 7,100' of Gain and 7,100' of Loss. .

This is NOT a race. Human Potential Fat Asses were built with the spirit of camaraderie and community in mind. While we encourage you to run at a pace comfortable to you, we ultimately promote these events as loosely organized group runs.
