MoMoFo 100k and 20 mile Fun Run

The event takes place June 4-5, 2027, in Morgan Monroe State Forest, Martinsville, Indiana. It offers two race options that use a roughly 20 mile loop through old growth forest, natural rock formations, lakes, and creeks. The 100 km race is an evening-start trail event with about 8,500 feet of climbing and a 20 hour cutoff. Course surfaces are approximately 85% single track, 11% forest service road, and 4% paved road. Southern Indiana summertime heat and humidity are noted as typical conditions.

The 20 mile fun run uses the same loop as the 100 km course and provides the same aid station support, with a 6 hour 30 minute cutoff for the single loop. The 100 km race is open to ages 14 and over. Both the 100 km and the 20 mile events are listed as UTMB index races and will award index points. Additional event features mentioned include participant items for finishers and a community fundraising appeal to purchase portable AEDs for aid stations.
