MoMoFo 100k and 20 mile Fun Run with Virtual Options

MoMoFo is a trail event in Morgan Monroe State Forest near Martinsville, Indiana. The in-person program includes a 100 km trail race and a 20 mile loop referred to as the fun run. The 100 km course totals about 8,500 feet of climbing and is composed of roughly 85% single track, 11% forest service road, and 4% paved road. The 100 km race has a 20 hour cutoff. The 20 mile loop follows the same route used by the 100 km event and has a 6 hours 30 minutes time limit. Aid stations are provided along the shared loop.

Virtual options are available for both distances. Virtual participants may complete the chosen distance between May 1 and June 7, using recorded data from smart technology with GPS recommended. Virtual results can be cumulative or completed in a single effort. Virtual finishers will receive mailed items that include a sticker, a T shirt, and a wooden finisher medallion or coaster; swag is scheduled to be mailed no later than June 14. The event is listed to award UTMB index points for both the 100 km and the 20 mile fun run. Visit the organization's website for the most recent information.
