Race Highlights

East Coast's most technical 100
Consistently ranked the most technical 100-miler in the East, with loose boulders and sharp rocky singletrack throughout both loops.
18,500 ft of climbing
About 10 major climbs of 750+ vertical feet each, with the longest gaining 1,550 feet over 2.5 miles.
Figure-eight double-loop design
Two connected ridgeline loops start and finish at Caroline Furnace — a rare course topology that creates a distinctive pacing and mental challenge.
Gold buckle for 10-year finishers
Finishers earn silver (sub-24h) or pewter buckles, but the rare gold buckle is reserved for 10-time finishers — a cult tradition at MMT.
Bird Knob summit at night
Most runners reach the 2,835 ft high point (mile 81) in darkness, with views over the Shenandoah Valley after hours of relentless rocky ridgeline.

Finish Awards

Sub-24 Silver Belt Buckle
Awarded to all finishers who complete the course in under 24 hours.
Finisher Pewter Belt Buckle
Awarded to all finishers between 24 and 36 hours.
10-Year Gold Belt Buckle

Crew Access Points

Pacer Rules

  • Pacers may join at Camp Roosevelt (mile 63.5) or any crew-accessible aid station beyond it.
  • Pacers may join at Habron Gap (mile 54) after 6:00 PM on Saturday.
  • Runners aged 62 or older may have pacers starting from Elizabeth Furnace (mile 33.3).
  • Only one pacer permitted per runner at any time.
  • Pacers may only join at designated aid stations — not mid-course.
  • Pacers must stay with their runner at all times and may not carry the runner's water, food, or gels — pacers are companions, not mules.

Crew Rules

  • Crew access is permitted at approximately 8 of the 15 aid stations. Drop bags are accepted at 10 aid stations.
  • Crews may not access all three southern Route 211 area aid stations — they are too close together. Only some are crew-accessible.
  • Crews must not meet runners anywhere other than designated aid stations — no roadside stops on course dirt roads.
  • At the Visitors' Center and Picnic Area aid stations, crews are limited to one vehicle with a parking pass issued at runner check-in.
  • Crews failing to comply with parking instructions may be excluded from that aid station or all subsequent stations, and the runner may be disqualified.

Based on historical averages for May 16

Mid-May in Virginia's Shenandoah Valley brings warm days and cool nights. Expect temperatures of 55–75°F during daylight hours, dropping to 40–55°F overnight on the exposed ridgelines. Spring thunderstorms are possible, and rain can make the already technical rocky terrain especially treacherous. Humidity is moderate to high. Runners will experience all conditions over the 24–36 hour window — warm afternoon sun, cool night air at elevation, and potentially wet trail surfaces.
