Why runners love it
- Volunteer club race since 1995 with no sponsors and a $250 entry for 100.6 mi (161.9 km).
- A 36 h limit for 5,639 m (18,500 ft) of gain is about 21 min per mile.
- 15 aid stations with hot food; about 9 or 10 take drop bags and 8 or 9 allow crew.
- High point is only 864 m (2,835 ft), so altitude is not an issue.
- Counts as a Western States qualifier, and pacers may join from mile 54 (87 km).
Watch out for
- Rocks are constant: leaf-covered, slick and ankle-rolling, with steep rocky descents in the dark.
- Longest gap is Habron Gap to Camp Roosevelt, 9.9 mi (15.9 km); its cutoff pulled runners before.
- 13 timed cutoffs, and the course page marks some as recommended only, so confirm which are enforced.
- Humid heat and thunderstorms are common in mid-May; 2009 brought hail and swollen streams.
- Entry opens 31 October at 08:00 and is capped at 250; a waitlist starts once it fills.

What runners and reviewers say
- iRunFar, Classic U.S. Ultras: MMT 100 (2020)Raced 2020 · article · Positive
Rocks that nag every mile are the defining feature. There are no big climbs and few views, which some find monotonous. Humidity and afternoon thunderstorms are common. The 36 h limit is generous, and the club volunteers and no-sponsor ethos keep the vibe warm.
“MMT's signature feature is its rocks which constantly nag you.”
- Karen Taber, MMT 2011 reportRaced 2011 · blog · Positive
First 100, finished in 35:28, about 32 minutes inside the 36 h limit. Rocks were hard on her feet, with a lost toenail and seven blisters. Aid was plentiful and friendly, a pacer from mile 63 (101 km) and a husband-crew carried her. Humid day, overnight rain, and a downpour in the last 3 mi (5 km).
- Kate Abbott, MMT 2010 reportRaced 2010 · blog · Mixed
Very rocky with steep descents; she scuttled down some in the dark. She and a partner stopped at Habron Gap (mile 53.6 / 86 km (53.4 mi)) after judging the 3:05 am Camp Roosevelt cutoff out of reach. Hot day at 73 F (23 C) at the start, aid with potatoes, quesadillas and cola.
- Massanutten Midnight Madness (2009 pacer report)Raced 2009 · blog · Mixed
Hot and humid day followed by thunder, hail and heavy rain; streams ran high at night. A runner and her pacers lost cushion, then were timed out at the 2:15 am cutoff near mile 65 (104 km). Volunteers coached with practical advice and soup and coffee.
- Dartmouth runtales, MMT 1995Raced 1995 · blog · Positive
Inaugural 1995 report: around 80 mi (129 km) of very rocky trail on a course with more than 16,000 ft (4,900 m) of climbing. Described as well marked and scenic. The writer finished 18th in 30:48 and says he would not have entered had he known how hard it was.
“A very tough race on a very scenic and well-marked course.”
