MoMoFo100k

The MoMoFo 100k and 20 mile Fun Run is a challenging trail running event held in Morgan Monroe State Forest, Martinsville, Indiana. The 100k race features about 7,500 feet of elevation gain over a course that is 85% single track, 11% forest service road, and 4% paved road, showcasing old growth forests, rock formations, lakes, and creeks. Starting in the evening, runners have a generous 20-hour cutoff to complete the race.

For those seeking a shorter adventure, a 20-mile loop fun run follows the same course with a 6.5-hour cutoff. Virtual race options are also available, allowing participants to run remotely. The event emphasizes a friendly, supportive trail running community and true Hoosier hospitality. Visit the organization's website for the most recent information.
