The course

Where it goes loop · 16 aid stations

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

Debuted in 2024: extends the 50-mile course out to a Robinson Gap turnaround for a longer, harder distance with a stout 17-hour cutoff.

Debuted in 2024; extends past the 50 Miler's Reservoir aid station on to a Robinson Gap turnaround before rejoining the 50-mile route. DISTANCE DISCREPANCY: branded "100K" (~62.1 mi / 100 km) but the race's own aid-station chart gives a cumulative finish mileage of 64.52 mi (~103.8 km). Home page brands it "100k++" and separately quotes "roughly 64 miles and 11,000 feet of climbing."

The race

What this one is

A trail ultramarathon starting and finishing at the Montebello Campground in Montebello, Virginia, run on gravel and jeep roads and singletrack in the Blue Ridge Mountains (George Washington National Forest). Offered at three distances from the same start/finish: 50 Mile, 50K, and 100K. Part of the Lynchburg Ultra Series alongside Holiday Lake, Terrapin Mountain and Promise Land, and traditionally the series' final race, held the first Saturday in November.

Founded in 1983 by David Horton, who wanted a 50-mile race along the Appalachian Trail from the James River to the Tye River; when the National Park Service would not permit a race on the AT, US Forest Service rangers helped him design a course finishing at the Montebello Country Store instead. The inaugural race had 21 starters and 13 finishers. Horton directed the race for 25 years before handing it to Clark Zealand in 2008. The race was cancelled in 2020 (COVID-19), the only cancellation in its history, though a group of locals ran an informal 50K fatass course to keep the streak alive. Jordan Cooter, Tim Spaulding and Brenton Swyers became co-race-directors in 2022. A 50K option was added in 2021 and a 100K option debuted in 2024.
