12 Hour Team Relay (2 or 4 person) and 12 hr solo ultramarathon

Please check the race website from time to time as new updates pertinent to the race will be posted there.

Welcome to our 8th year!
The Night Crawler Endurance Challenge is central Wyoming's only solo ultramarathon and team relay. Run overnight under the light of the moon through the forested trails atop beautiful 8,100-foot Casper Mountain. Run as a solo ultrarunner, or get your fellow night crawling friends together for a 2 or 4-person relay team.
The Night Crawler begins at 6:30 PM on Friday evening continuing throughout the night and finishes at 10:30 PM (4hr solo) or 6:30 AM on Saturday as the sun rises. Enjoy the camaraderie of our awesome trail running community and the scenery that our mountain gem has to offer. 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 or your team can or chooses to.
