Wyoming Range 100-Mile Endurance Run

2025 annoucements

Lottery registration should now open on January 13th at 10:00am MT

We continue to work through out Forest Service permit, so we’re pushing our lottery back to Monday, January 13th at 10:00am MT. We’ll keep the lottery open for two weeks — through Sunday, January 26th at 10:00pm MT.

Pencil in August 8-10 on your calendar

We are tentatively planning to host the 2025 Wyoming Range 100 on Friday, August 8th through Sunday, August 10th.

“Tentatively” because we’re still working through our permit with the U.S. Forest Service. Great things take time.

Stay tuned for details on our lottery

We are spending a lot of time thinking through how to structure our lottery. We’ll likely borrow a few concepts from other races as well as cook up some of our own.

Dedicated to the landscape

Tucked away in southwest Wyoming, below the Tetons and above the Wasatch, sits the Wyoming Range. This stretch of mountains is home to the Wyoming Range National Recreation Trail (WRNRT), a 75-mile stroll through some of the most beautiful high country imaginable. The WRNRT sits at the heart of the Wyoming Range 100, giving runners the opportunity to immerse themselves in wilderness while still running a supported race.

Built for a grueling finish

With 24,000’ of climbing and an average elevation of 8,500’, prepare yourself for a grueling run that offers few breaks. Don’t worry too much, though — time is on your side. With a generous 48-hour cutoff, we want every runner to complete the 105-mile epic. We designed the Wyoming Range to be challenging but finishable.

Hardock 100 qualifier

The legendary folks at the Hardrock 100 asked if the Wyoming Range 100 would to join the “wild and tough” ranks of Hardrock qualifiers. After talking with key stakeholders, we proudly said, “Count us in.”

This is a graduate-level race with no shortage of challenges. You'll run in grizzly country. You'll have ten-mile stretches between aid stations. You'll cover rough and disappearing trail. You could run through snow, lightning, and white-out conditions. At this race, you must be prepared for everything.

Of course, if you’re considering the Wyoming Range 100, please do not sign up simply because it’s a Hardrock qualifier. We want you to cherish our event and the landscape through which it runs on their own extraordinary merits.
