From the Field
It's a beast absolutely not for the faint-hearted you need previous gravel experience if you're gonna try to tackle the full 131 miles.

It's been really intimidating because we've only had the full 131 distance which isn't for everybody now the event has tripled its registration and we have three distances that writers can choose from we have a 40 mile distance a 70 mile distance and the full 131 mile.

Frequently Asked Questions
What is the climate like at WYO 131?
September conditions create variability through the washboard middle section where "winds usually pick up" during the traditionally rough miles 60-90. The 6 AM lights-required start suggests weather window management at Wyoming altitude. Race warnings emphasize proper preparation for conditions spanning "vast sagebrush plateaus" to "subalpine terrain." Similar climate challenges to SBT GRVL.[2]
How are the logistics for WYO 131?
Race-day packet pickup from 5:30-7:30 AM for a 6 AM start cuts it close for 131 miles. The course website warns riders are "RESPONSIBLE FOR YOUR OWN NAVIGATION" and that participants "MAY HAVE TO WAIT UNTIL A COURSE MARSHALL IS AVAILABLE" if picked up by sweepers. No airport, lodging, or parking details provided for remote Lander.[2]
How adventurous is WYO 131?
The route delivers "131 miles of pure, untamed adventure" through towering Wyoming Hoodoos at mile 36.5 and the historic gold mining town of Atlantic City at mile 90. Riders traverse "everything from fast-rolling gravel to chunky, soul-crushing sections" before the "wicked, white-knuckle descent through Sinks Canyon State Park." Crew-accessible bail points when Wyoming backcountry exceeds capability.[2]
How prestigious is WYO 131?
Chris Mehlman's 7:04 course record and Caroline Weiler's 9:05 women's mark reflect a small competitive field without major pro presence. The race philosophy "Ride hard. Live easy. Wave often" emphasizes Wyoming authenticity over national recognition. Multi-distance options from 13 to 131 miles serve local community over elite competition building.[4]
Should I race WYO 131?
If you're in Wyoming or the Rockies and want an ultra-distance challenge—yes, it's a well-organized event with genuine wilderness appeal. If you're traveling from far away—there are more prestigious ultra events elsewhere.
