Description:

We will officially be hosting the Night Crawler out of the Start/Finish/Lap area in the Nordic stadium near the new Casper Mountain Trails Center (9301 Casper Mountain Rd.) We will have access to the new Trails center Parking Lot. See the new course on the course tab…
We will only be offering the 4 hour and 12 hour solo options for this year. We’re excited to see you all again for year 9 on Fri. Aug. 22, 2025!

The Night Crawler Endurance Challenge is central Wyoming’s only solo ultramarathon event that is run overnight. Run through the forested trails atop beautiful 8,100-foot Casper Mountain. Run as a 4HR or 12HR solo ultra-runner.
The Night Crawler begins at 6:30 PM on Friday evening continuing throughout the night and finishes at 6:30 AM on Saturday. Set up a tent, hammock, or chair in the start/lap/finish area and take a break between laps to enjoy the camaraderie of our awesome trail running community. Are you up for the challenge?
The Challenge…
Participants will follow a scenic, rolling race course atop Casper Mountain. The course consists of forested single track and cross-country ski trails, with minimal-moderate technical difficulty… Perfect for a run at night!

The event will begin under a beautiful August sunset, continuing throughout the night under the illumination of your headlamps and the moon, finishing as the sun rises revealing the alpen-glow of our stunning mountain gem. Participants will switch directions every lap, (“washing-machine” style), with odd-number laps (1,3,5 etc.) run clockwise and even-number laps (2,4,6 etc.) run counterclockwise.
