Out of the Darkness & Into the Bighorns Hyattville to Ten Sleep UltraMarathon

Join us for some mountain therapy in the beautiful Bighorn Mountains and Ten Sleep Canyon for our sixth annual Out of the Darkness & Into the Bighorns event!! 

We have been able to donate a total of $5000, with an additional $1000 match from Blue Cross Blue Shield for WyoGives, for Cloud Peak Counseling Center for their free walk-in clinic and their new Crisis Stabilization Center in Worland, thanks to all of our amazing sponsors and our registrants! We hope to raise that much this year to continue to support these suicide prevention efforts that our entire state is able to utilize.

Out of the Darkness & Into the Bighorns is operated under a special use permit with the Bighorn National Forest and is an equal opportunity provider. 

2024 Race Details

 2024 REGISTRATION OPEN!!!
Please join us for the Inaugural Hyattville to Ten Sleep UltraMarathon on July 6, 2023!!!

This course was cancelled in 2023 due to low registration, and we take responsibility for that, getting a late start with weather verifying the mileage and vert on this course.

We are so excited to announce that we officially have enough registrants to GUARANTEE that the Ultra event is happening this year!!

This Ultra epitomizes Wyoming scenery! Hyattville is unmatched in charm and beauty as you start in the desert at the Hyattville Logging Road and run up into the red foothills and into the unique sandstone and limestone rock formations overlooking the epic Big Horn Basin. It's a very steep start, with 1600 ft in elevation gain in the first 9 miles.

This is my favorite view in Wyoming, you can see all of the mountain ranges that encircle the Basin and all of the badlands, winding rivers, farms and red hills below. You will continue up into the Bighorn National Forest and get a taste of the diversity of our ecosystems as you run higher into the Bighorn mountains and back down through the Ten Sleep Canyon to finish at the Ten Sleep Hatchery.
