The course

Where it goes loop · 4 aid stations

Course line from the race's own GPX. Source file.

Start of ALL races -> Section 1 (7.1 mi) to Wolfkiel Run AS#1 -> a blue-flagged cutoff trail across Miller Farm Bridge directly to AS#3, skipping AS#2/Petroleum Center and the Cow Run water stop entirely -> Section 4 off-trail, around Drake Well, back the paved bike path to the TMS finish.

The race

What this one is

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.
