One loop of the base 50K course: TMS -> 1.5 mi asphalt to the Gerard Hiking Trail (GHT) trailhead -> south on the west GHT to Wolfkiel Run AS#1 (7.1 mi) -> Egbert Farm/Petroleum Center AS#2 (13.9 mi, the turnaround) -> north on the east GHT past Cow Run Shelters (unstaffed water, ~18.9 mi) to Miller Farm Rd bridge AS#3 (22.7 mi) -> past the Course Marshal tent (unstaffed water, ~28.7 mi) near the Drake Well entrance -> back across Jersey Bridge and the paved bike path to the TMS finish/AS#4 (31.1 mi).
Four concurrent races (25K, 50K, 100K, 100 Mile) on an approximately 50K counter-clockwise loop run mostly on the single-track Gerard Hiking Trail of Oil Creek State Park near Titusville, Pennsylvania, plus short paved bike-path and side-street sections linking the trailhead to race HQ at Titusville Middle School. The valley is the site of the world's first commercial oil well, drilled by Edwin Drake in 1859.
Race-results page lists entrants data back to a 2009 running (84 registered, 80 started); the home page for the 2026 edition calls it the '17th running,' which would put the first year at 2010, one year later than the earliest results entry -- recorded as a conflict, not resolved. The 100 mile race has repeatedly served as an RRCA Pennsylvania (and in some years Eastern Region or National) Ultra Championship race, per the year-by-year entrants list on the results page.

oc100trailruns.orgNobody 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.
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.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
