Niwot's Challenge
Sedalia, United States • 2 May 2026
Event Overview
Niwot's Challenge is not a traditional race but a navigational adventure on Colorado's Front Range. The event has a runner capacity of 40 and takes place along the South Platte River near Sedalia, Colorado.
The Experience
The course is not published in advance and navigation requires a map and compass, as GPS devices are not allowed. Participants must find specific "Sacred Waypoints" along the route to retrieve unique codes. The event emphasizes self-reliance, with minimal aid available. It is described as suitable for participants with significant experience in ultrarunning, orienteering, or adventure racing.
Participation Levels
There are three levels of participation, each with its own time limit and distance.
- Burn "Training Run": A loop of approximately 24 miles with 10,000 feet of elevation gain, to be completed within 16 hours.
- Chief's Status "Fun Run": Completion of both the Burn and Chief's loops, totaling approximately 50 miles and 20,400 feet of elevation gain, within 30 hours.
- Deity Status: Completion of both loops twice—once in each direction—totaling approximately 100 miles and 40,800 feet of elevation gain, within 60 hours. A prize purse is offered for the first person to achieve this.
