UltraSignup registration stays open, but entry is via a rolling waitlist draw rather than guaranteed sign-up: "Over the Halloween weekend we selected the spots in the 2026 field... you can register TODAY... get on the waitlist and you could be chosen NEXT. Lots of people withdraw before the race." 502 people were on the UltraSignup roster as of this research (Aug 2026), against a reported 500-runner cap.
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
loop · 3 aid stations
The full Barkley Fall Classic distance. Published as a 50-kilometer race, but the actual distance is not fixed: the course is redesigned every year and not revealed until the night before, and GPS-watch accounts from individual editions have recorded distances well past 50K. A cutoff at the course's Decision Point diverts any runner who has not reached it in time onto the Marathon course instead of pulling them from the race.
The race
What this one is
A 50-kilometer race at Frozen Head State Park, Wartburg, Tennessee, created by Lazarus Lake and Steve Durbin to give runners "a taste of what the Barkley Marathons is all about": the same mountains, some of the same signature climbs, a course map withheld until the night before, and no GPS. Runners who miss the cutoff at the course's Decision Point are diverted to a shorter Marathon finish rather than pulled from the race.
Founded in 2014 by Lazarus Lake (Gary Cantrell, creator of the Barkley Marathons) and Steve Durbin of Durbin Race Management. The 2026 edition is billed by the race itself as "Barkley Fall Classic XIII" (its 13th running), which is consistent with a 2014 first year. UltraRunning Magazine's results archive for the race begins with a "30 Miles" category in 2014, switching to "50 KM" from 2015 onward.

Pacer rules
"No pacers or running as bandits. Friends and family are NOT allowed to run with you. Running on areas that are not marked park trails subjects you to possible arrest, and citations being given to you by Park Rangers."

"Drop bags are not allowed. Caching is not allowed."

Cutoff philosophy
"The Decision Point is exactly that. You decide if you wish to continue on in pursuit of the Croix de Barque, or take the marathon finish. IF you decide to continue, it's all or nothing... you'll either finish in time for the Croix, or receive nothing but admiration that you went for it." There is no partial credit for attempting the 50K past the Decision Point: a runner who continues and does not finish in time receives a DNF, not a marathon result.

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: 77 sources for this race. Hover a source link to read the sentence it came from.
41% 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.
