Event overview
The MoMoFo event in Morgan Monroe State Forest, Martinsville, Indiana, runs on June 5-6, 2026. The event offers two on-site trail distances:
- 100 km
- 20 miles
The 100 km race is run on trails with a 20-hour cutoff and is open to ages 18 and older. The 20-mile fun run is a single loop that shares course sections with the 100 km and has a 6.5-hour cutoff to complete the loop. The event is a UTMB index race for both distances.
Course and virtual options
The course is mostly single-track and natural trail: about 85% single track, 11% forest service road, and 4% paved road. Total climbing for the 100 km is listed at about 8,500 feet. The route passes through old-growth forest, natural rock formations, lakes, and creeks; southern Indiana summer heat and humidity are noted as possible conditions.
Virtual options are available for both distances. Virtual participants may complete their chosen distance between May 1 and June 7 and must record and submit activity data, with GPS preferred. Virtual finishers receive a sticker, T-shirt, and a wooden finisher medallion/coaster; swag will be mailed by June 14. Results are submitted for virtual entries, but no awards are offered. Additional fees include 7% tax. Visit the organization's website for the most recent information.
