The Night Crawler 12-hour Endurance Challenge is a 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 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? https://nightcrawler12-hourec.weebly.com/
