View source for 2009 Massanutten Trails 100

The MMT100 is generally considered the toughest 100 mile race east of the Rockies, and one of the toughest in the US. Some of that toughness comes from the elevation change, which is about 20,000 feet of ascent and the same descent. However, the real challenge is the rough trails. Some of the trails are good running, and some of the trail is rocky and you have to work on where to put your feet. However, a significant portion of the course is so rocky there is nowhere flat to put your feet. For many runners, a good chunk of MMT is not runnable; in fact, it is tough walking, let alone running.
