2024 registration

January 4, 2024

I have been honored, surprised, and floored by the number of folks who have reached out, asking our team when we’ll open registration for 2024. As with years past, our plan has been to open registration in January.

This year, however, will be different. We don’t have a concrete registration date — and may not have one for the foreseeable future.

As of late last year, the wolverine is officially an endangered species — which is a good thing! — and the Wyoming Range is among the few areas in the lower 48 where wolverines live. Accordingly, the Forest Service has to reassess our permit for potential adverse impacts to the wolverine and its habitat.

This review process — which requires the work of many, many dedicated professionals — takes time. And we don’t know exactly how much time.

Best case, I’ll take down this message in mid-February, and y’all can register in droves. Worst case, I’ll open 2025 registration a year from now. My base case, though, sit somewhere in the middle.

Please bear with us. We’ll share updates in as close to real-time as possible here and on UltraSignup. If you email me for an update, I’ll direct you to this note (which we’ll timestamp, so you can track updates).

I’ll close by offering (unsolicited) advice as a fellow ultra-runner. While I am confident the Wyoming Range 100 will happen in 2024, I wouldn’t encourage anyone to wait on registering for a different event. In other words, if you have your eye on another race this year, I suggest you take a closer look. Ultimately, I don’t want to leave anyone at the alter.

Thanks for the continued support, folks.


"Graduate-Level" Race & Hardrock Qualifier

This is a graduate-level race with several unique challenges. You'll be running in grizzly country (with bear spray). You'll have long stretches between aid stations. You'll encounter rough trail that may involve way-finding. You could run through snow, lightning, and white-out conditions in the clouds. Be prepared for a grueling challenge.

But you'll be rewarded for your finish with a Hardrock qualifier!

The Course

A rugged and relentless 100-miler along the Wyoming Range National Recreation Trail.

The Wyoming Range National Recreation Trail (WRNRT) travels north-south for 75 miles through some of the most beautiful high country imaginable. We placed the WRNRT at the heart of the Wyoming Range 100 to offer seasoned ultra-marathoners the rare opportunity to feel immersed in deep wilderness while still running a fully supported race.

But this is no ordinary race. With 28,000’ of climbing and an average elevation of nearly 9,000’, you should prepare yourself for a grueling run that rarely offers breaks. By the time you reach the finish line, your belt buckle will have been hard-earned many times over.

Service Requirement

All entrants must complete eight hours (or more!) of trail work at least two weeks prior to race day. We will validate trail work with this form. If you find yourself in the Jackson, WY area, we encourage you to contact Friends of the Bridger-Teton for local trail projects.

Group-based trail projects are hard to come by these days, so we’re offering a workaround: Donate $80 to Friends of the Bridger-Teton and send us your donation receipt. We hope these options make it easier for you to satisfy your service requirement (which we take seriously).


$320.00. The price will not increase as race-day approaches.
