100 Miler registration on UltraSignup is marked 'Closed Aug 20 @ 11:59 PM' while the 50K listing on the same page is marked 'Open' at the same time; the page's own text is internally inconsistent about which distances are still open 14 days before the race. Recorded as a conflict, not resolved.
Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this.
Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course
Where it goes
out and back · 3 aid stations
An out-and-back from Cispus Learning Center up to the historic Burley Mountain Fire Lookout and back, 13.82 measured miles with 4,356 ft of gain / 4,238 ft of loss. Runs the same day as the 50K. A beginner-friendly introduction to mountain racing with a leisurely 9-hour cutoff.
Separately, the linked 'Aid Stations 2026' PDF for this course is headed 'Dark Divide 50K Trail Run' and dated 'Saturday, September 6, 2025' (a full year off and the wrong race name) -- almost certainly an un-updated template left over from a prior year. Its station list, per-leg mileage/elevation and 9-hour cutoff total are used because they match the live 2026 page's own prose ('9 hours to finish') and the course GPX/course-sections document exactly; its date and race-name header are not used for anything.
The race
What this one is
A wilderness trail-race weekend (100 Mile, 100K, 50K, 15 Mile) through the 70,000+ acre Dark Divide Roadless Area in the Gifford Pinchot National Forest, based at the Cispus Learning Center near Randle, Washington. The 100 Miler is a Hardrock 100 qualifier.
Wonderland Running founder Sean Harrasser has run the race since its start; a 2026 Facebook post from the organizer calls the 2026 edition "year six," placing the first edition in 2021. The race is dedicated in part to the memory of five-time Hardrock finisher Mike "Bushwhacker" Burke.

Nobody sees it until we have read it. No account, no sign-in.
See something wrong or out of date? Suggest an edit.
This changes nothing on the page on its own. Somebody checks it against the race first.
Seen a course preview or a film of this one? Send it over.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
Have the GPX? Send us the link.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
Are you the race director? Get in touch and we'll make it right.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
Where this came from.
Every fact on this page records its source and when we last checked it: 89 sources for this race. Hover a source link to read the sentence it came from.
51% of what we track for a course is filled in. The rest says "not checked yet" rather than guessing.
Ultras change. We will tell you when this one does.
Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.
No account, and nothing to cancel.
What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.
I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
