MoMoFo 100k and 20 mile Fun Run with Virtual Options
About the Event
This 100km trail race will prove that there’s more than just corn in Indiana! Situated in Indiana’s beautiful Morgan Monroe State Forest, this evening-start event will have plenty to offer throughout the night with its old growth forests, natural rock formations, lakes, and creeks. Oh, and did we mention the hills? With about 8,500 feet of climbing—yes, over 8.5k of climbing!—in addition to southern Indiana’s typical summertime heat and humidity, this race is tougher than you’d think. Comprised of 85% single track, 11% forest service road, and 4% paved road (but with a generous cutoff time of 20 hours), we assure you that you won’t be disappointed.
For those less adventurous trail nuts we offer up our “fun run”. If you aren’t quite up for the full 100km we have a 20 mile loop for you to “enjoy”. This run will start Saturday June 6 at 8:30am. You will have a SUPER generous 6 hours and 30 minutes to complete one loop. This is the same loop as the 100k folks with the same unbelievable support at each aid station.
We invite you to experience true Hoosier hospitality with our fun and friendly trail running community.
Come help make this a trail party…WooHoo!
Ready to test your limits? The MoMoFo 100k and 20 mile Fun Run with Virtual Options brings a highly anticipated Ultra, 32.2K to Martinsville on June 5, 2026. Expect a fantastic route right in the heart of Indiana.
