The course

Where it goes loop · 10 aid stations

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

The "little sibling" to the 50 Miler, introduced in 2021, covering roughly the front half of the 50-mile course plus the Mount Pleasant Loop.

Covers roughly the front half of the 50-mile course plus the Mount Pleasant Loop; introduced in 2021. DISTANCE DISCREPANCY (notable): branded "50K" (~31.1 mi / 50 km) but the race's own aid-station chart gives a cumulative finish mileage of 34.5 mi (~55.5 km) -- nearly a 50% overage versus the nominal 50K distance. A runner's own account (HMRRC Pace Setter, Jan 2024) independently describes it as effectively "55K." The home page brands it "50K++" acknowledging the overage.

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.

Drop bag rules: FAQ names only "MMTR, 50 Miler and 100K distances" as eligible for drop bags; the 50K route does not pass Long Mountain Wayside (the only drop-bag station), so recorded as not offered on this course. runmmtr.com
