The Night Crawler Endurance Challenge is an exciting ultramarathon set atop the breathtaking Casper Mountain at an elevation of 8,100 feet. Participants can choose between 4-hour and 12-hour solo options, running through scenic forested trails under the stars. This unique overnight event invites runners to enjoy a fun and supportive atmosphere within the Nordic stadium area, providing a perfect backdrop for camaraderie and connection among trail enthusiasts. Runners can complete as many laps as they desire within their chosen time frame, with the flexibility to rest as needed in designated areas. There's no pressure to finish at a specific pace—just the encouragement to enjoy the challenge and run however long feels right. The absence of a DNF makes this a welcoming experience for all athletes.
