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 using a map and compass, with limited aid available. The race includes off-trail miles and emphasizes self-sufficiency, making it unsuitable for beginners.

Runners can aim for various achievement levels, including "Chief" and "Deity" status, based on their performance. The event fosters a unique community spirit, with participants encouraged to attend preparatory "Book Settings" to familiarize themselves with the course.
