Description
2025 update:
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?
There is no such thing as a DNF with this event.
The format of this event allows participants to run the course and rest as they choose. We only ask that you notify race organizers if you are taking an extended break between laps or are done before the finish at 10:30 PM or 6:30 AM so that we don't have to send a search party out for you. Aside from that have FUN and run as many hours/laps as you can and feel good about it!
Participants DO NOT need to run for the whole 4 or 12 hours. That is simply how long you have to complete as many laps as you can or choose to.
