Night Crawler Endurance Challenge
The Night Crawler Endurance Challenge is an overnight, time-based trail event held on Casper Mountain in Casper, WY on August 14 to 15, 2026. The course runs on forested trails near the Casper Mountain Trails Center and uses the Nordic stadium area for the start, lap, and finish zone. The venue includes access to the Trails Center parking lot and space for participants to set up tents, hammocks, or chairs in the lap area.
Organizers offer multiple formats so participants may choose how long to be on course. Options include:
- 4 hour solo
- 12 hour solo
- 12 hour 4 person relay
Online registration closes August 12, 2026. Late registration is available at packet pick-up on August 13 for an additional fee; there is no race day registration. The event is presented as central Wyoming’s only overnight, time-based solo and relay trail event and will be run at approximately 8,100 feet elevation on Casper Mountain. Organizers note that participants may run and rest as they choose, and that the event does not use a DNF designation; every participant receives a finisher award. Awards for top overall female and male categories and relay teams will be given after the race. Sponsors listed for the event include WYRun, Complete Physical Therapy, Switchback Electrolytes, Ben Winckler Photography, and Oil City News.
