Start at Asaph, out-and-back north to Wellsboro Junction (~6 mi each way), back to Asaph, then out-and-back south to Blackwell (~19 mi each way) -- one full 50-mile lap -- repeated twice for 100 miles and 4 passes through the Pine Creek Gorge canyon section.
Course is a converted rail-trail: finely crushed limestone, 20 ft wide, ~2% average grade (900 ft loss over the full 63-mile trail, not all of which is on this course). Marketed and widely reported as flat and beginner/first-100-friendly, but one entrant's caveat is worth keeping: "flat course doesn't always mean easy course." The Darling Run to Blackwell leg (used, e.g., by a solo relay runner since no exchange is allowed at Tiadaghton) is 16.9 miles, the longest gap between any two aid stations on the course.
An out-and-back ultra on the Pine Creek Rail Trail through the Pine Creek Gorge (the "Grand Canyon of Pennsylvania") near Wellsboro, PA, run concurrently at four distances (100 Mile, 100K, 50 Mile, Marathon) from a shared start/finish at Asaph. The trail is finely crushed limestone, 20 feet wide, closed to motor vehicles, and loses only about 900 feet over 63 miles (a 2% grade) -- flat enough that the race markets itself as beginner-friendly and a common choice for a first 100-miler.
First run at least by 2011 (UltraSignup results are on file back to 2011). The 100-mile course was originally longer: a 2013 crew report describes the out-and-back continuing south past Blackwell through Slate Run and Cedar Run aid stations to a turnaround near the village of Cammal (Blackwell was passed at mile 79.1, not the turnaround). By 2016 (per an archived course-map image) and continuing through the current 2026 listing, the course has been shortened to turn around AT Blackwell, with the Slate Run/Cedar Run/Cammal stations no longer part of the race.

sites.google.comNobody has been out there with a camera or a microphone yet. A gap means nobody has found it, not that it is not out there. Seen a course preview or a film of this one? Send us the link.
Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
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.
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.
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.
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.
