Night Crawler Endurance Challenge

The Night Crawler Endurance Challenge is a unique overnight solo ultramarathon held in Casper, Wyoming, on Casper Mountain at an elevation of 8,100 feet. Participants can choose between 4-hour and 12-hour solo running options, navigating forested trails starting and finishing at the Nordic stadium near the Casper Mountain Trails Center. The event fosters a supportive atmosphere where runners can rest between laps in a communal area with tents and chairs. The challenge emphasizes personal achievement with no official "Did Not Finish" status, encouraging runners to complete as many laps as they can within their chosen time frame. The race is in its ninth year and offers finisher awards and special recognition for top male and female runners. Visit the organization's website for the most recent information.
