Number of participants
As a U.S. Forest Service permittee, the Wyoming Range 100 is capped at 100 runners.
Entry requirements
Minimum age
Entrants must be at least 18 years old on race day.
100-mile qualifying race
Lottery applicants must have completed at least one official 100-miler within the past five years. If you’re unsure what “official” means, just ask.
Similarly, if you don’t have a qualifier but think you’re capable of successfully completing the run, give us a shout.
Stewardship work
Entrants must do one of two things once they’re on the entrants list:
Complete eight hours of trail or wildlife habitat restoration work: Entrants must complete at least eight hours. We’d be delighted for you to go over!
Donate $80 to Friends of Bridger-Teton: In lieu of trail work, entrants may donate $80 to our trail stewardship partner, Friends of Bridger-Teton. Every penny will support the great work they do in conjunction with the Bridger-Teton National Forest. If you choose this option, you must email us your receipt/donation confirmation.
Runners must report their stewardship work here.
Lottery
Philosophy
Great folks in and around the race — it’s as simple as that. We’ve designed our lottery to bring as many great people to the Wyoming Range as possible. We want tough runners, thrilled volunteers, and ecstatic supporters.
Process and timeline
| Day(s) | Step | Details |
|---|---|---|
| February 1-10 | Lottery opens | Runners will apply through UltraSignup during the ten-day apppication period |
| February 12-14 | Validate ticket count | Race management will publish ticket counts on this website, and runners will validate the count is correct |
| February 15 | Final ticket counts published | Race management will publish final ticket counts on this website |
| February 15 | Lottery bypasses published | Race management will announce the runners who bypass the lottery. We discuss bypasses below |
| February 16 | Execute lottery | We will assign a random number to each ticket. The minimum number will be 1 and the maximum will equal the number of tickets. Then, we'll generate a random reference number that’s between, but inclusive of, the minimum and the maximum. Finally, We'll order the tickets by how far their number is from the reference number. The ordering will assume that we are counting up, meaning that if the reference number is 17, 18 is the “best” number and 16 is the “worst” |
| February 17-20 | Accept lottery invitation | After the lottery, runners must accept their slot. If runners do not accept their spot, we will move folks off the waitlist |
| February 19 | Open waitlist | Race management will open a waitlist via UltraSignup |
Key details
No revisions to ticket counts
During the validation stage, you will not be permitted to adjust your ticket number in response to what you perceive as higher- or lower-than-expected “competition” — perhaps offering to bring an extra volunteer (see below) or backtracking on your offer to help mark course.
The validation stage is there to catch errors made by race management.
Honoring ticket commitments in the event of a deferral
If you get into race through the lottery but defer to the following year, your participation the following year will require that you honor any ticket commitments that you made in the prior year — for example, by bringing a volunteer.
How to improve your odds in the lottery
Each year, our lottery will include ways to increase your ticket count in the lottery. Repeat finishers, for instance, will receive bonus tickets. Runners who bring committed volunteers will also receive bonus tickets.
We will identify these bonuses before opening the lottery.
How to bypass the lottery
Be the prior-year John Langford award winner
Each year, we honor the resilience of last place — usually an unofficial finisher, after the 48-hour cutoff — with the John Langford award. In 2022, John Langford finished the WYR100 in 59:18:12 and has come to embody everything that we love about this race. We want to similarly honor those who have followed in John’s footsteps, gritting for longer than anyone, with an invitation to return the following year. This entry must be used in the following year and cannot be rolled forward.
We fully acknowledge that this lottery bypass presents a measure of moral hazard: “If I’m second to last, I’m second to last. But if I slow down, I get to bypass the lottery next year.” Out of respect for John and the race — don’t do that.
Be a good human
The race management team will award nine entries to folks who represent everything that we hope the race will someday embody. They could be amazing volunteers, prior-year finishers who didn’t get in through the lottery, or generally good humans whom we believe will elevate the event.
We’ll give two examples:
Eric and Henry: In 2024, Eric and Henry marked and swept over 40 miles of course. Then, they stuck around and helped us clean the finish area. They were an automatic entry in 2025
Michelle: Michelle is a three-time WYR100 finisher and spectacularly good human. In the unlikely event that Michelle does not get in through the lottery, we’ll welcome her with an RD spot
RD spots are not spots to which you apply, so please don’t ask for an RD spot.
Waitlist
After we run the lottery, we will activate a waitlist. Runners who are invited to join the race from the waitlist will receive an email from UltraSignup — you must accept the invitation within 48 hours to enter.
If you are not selected in the initial lottery, you will receive additional ticket(s) in the following year’s lottery. Runners who join the waitlist after the lottery will not receive additional tickets in the following year’s lottery.
Miscellany
Our lottery is subject to change on an annual cycle
Our lottery will be subject to change on an annul cycle. Once we’ve set it for a given year, however, we won’t alter it. But we reserve the right — and plan to exercise the right — to change it from one year to the next. The reason is simple: our lottery should reflect the shifting needs of our event and, secondarily, the broader needs of the trail running community.
If you email our team and request an exception, we promise you the answer will be, “No.” We welcome your feedback on our lottery, but you should assume that we’ll consider your suggestions in a subsequent year.
Exceptions to our 100-mile qualifier
Your race director, Denis Cook, ran his first 100-miler on a qualification exception and has a soft spot for them. But only if the runner has clearly done their homework, digesting every page on this website.
To request a qualification exception, please email Denis during the lottery window. If you email me beforehand, I will reply, “Please check back during the lottery window.” (Requesting an exception outside of the lottery window is a terrific way of signaling that you haven’t digested every page on this website.)
From there, we’ll schedule a 15-minute call, during which we’ll both assess if the WYR100 is right for you. It’s not right for everyone, irrespective of one’s running “resume.” Ultimately, we don’t want anyone to DNF their first 100.
No sponsorship spots (for now)
The WYR100 does not have formal sponsors. That’t not necessarily intentional and could change, depending on the long-term needs of the race. So, for now, we do not have sponsorship entries.
Looking ahead, we are open to partnering with like-minded organizations that understand what we’re trying to build and, equally important, how we’re trying to building it.
