Wyoming Range 100-Mile Endurance Run

Annoucements

Feb. 19: We’ll provide Garmin tracking devices this year

We use Garmin InReach devices to track runners. In prior years, to keep costs down, we invited runners to use their own Garmin InReach device, if they had one.

This year, we’ll provide Garmin devices to everyone. If you rented an InReach through UltraSignup, we’ll refund that amount after we’ve processed your registration.

Feb. 17: Accept your registration invitation from UltraSignup!

You can view the results on our lottery page. If you were selected in the lottery, you have until Tuesday, February 24th at 5:00pm MT to accept your invite from UltraSignup. After that, we’ll give your spot to the first person on the waitlist.

Event manual

Our event manual is our single-stop source of information about the race. It’s great for runners before the race — and pacers and crews during the race.

We’ll publish the 2026 manual in late May, after we’ve been able to assess the post-winter course conditions. In the meantime, you should consider the 2025 version a great starting point.

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 108-mile epic. We designed the Wyoming Range to be challenging but finishable.

Hardock 100 qualifier

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.
