Niwot's Challenge

Niwot's Challenge is a challenging ultramarathon held annually in Colorado's Front Range, designed for experienced runners. Modeled after the Barkley Marathons, this grassroots event features a secretive course that requires participants to navigate primarily off-trail using a map and compass. With a limited capacity of 40 runners, the event emphasizes self-sufficiency and decision-making, as aid is minimal.

Participants can aim for various achievement levels, including "Chief" and "Deity" status, based on the distance and difficulty of the loops completed. The event fosters a unique community spirit, encouraging camaraderie and adventure among its participants. Visit the organization's website for the most recent information.
