Why We Muck It

The “MS” part of MuckFest® MS stands for multiple sclerosis, a chronic and often disabling disease that attacks the central nervous system. MS is unpredictable and affects every individual differently. Women are two to three times more likely to get MS, and it affects over two million people worldwide. This is the reason we come together—to rally friends in support of people living with MS in our community. That's why 100% of funds raised by you benefit the National Multiple Sclerosis Society. Join MuckFest MS and have a blast while being a part of something that matters.
