MuckFest® MS is the FUN mud run with the best obstacles. No special training or equipment required: just bring a pair of sneakers and your sense of humor. We run on a well-designed 5K course, featuring awesome, super-sized obstacles and mud from start to finish. This event is built for laughs, but we’re also on a serious mission to support people living with multiple sclerosis and to bring us closer to a world free of MS. 100% of fundraising dollars go to the National Multiple Sclerosis Society.
