MoMoFo 100k and 20 mile Fun Run with Virtual Options

Embark on an unforgettable trail running adventure at the MoMoFo 100k and 20-mile Fun Run, set to challenge and inspire on June 5-6, 2026, in the heart of Martinsville, Indiana. Nestled within the scenic Morgan Monroe State Forest, this event offers a unique opportunity to explore a hidden gem of lush greenery and rugged backcountry trails, proving "there's more than just corn in Indiana."

The course is a demanding yet beautiful 20-mile loop, primarily single track (85%), winding through old-growth forests, past natural rock formations, and alongside serene lakes and creeks. Runners will tackle significant elevation changes, with the 100k race accumulating approximately 8,500 feet of climbing over its three loops. The 100k kicks off at 7 PM on Friday, June 5th, inviting participants to experience the unique challenge of navigating the trails under the night sky. The 20-mile fun run begins Saturday morning at 8:30 AM, offering a taste of the same "brutal and beautiful" terrain with a generous 6.5-hour cutoff.

Runners can expect exceptional support along the way, with four fully loaded aid stations and one water stop strategically placed less than five miles apart on each loop. This event is renowned for its "old-school charm" and vibrant trail-running community, where "Hoosier hospitality" is a staple, enhanced by a strong volunteer base and the infectious enthusiasm of Race Director Benny Hickock. Typical race day conditions in early June include highs around 79°F and lows around 58°F, with a 17% chance of precipitation, which can occasionally make for muddy and slick sections, adding to the course's challenging character. Virtual options are also available for both distances.
