Rally friends to muck it at MuckFest MS Philadelphia, the largest MuckFest MS event of the season. You and your friends will run, swing, slosh, climb & laugh your way through a 5K course of incredible obstacles and muddy pits, trenches and craters. It’s not just about the fun, there’s also a mission behind the muck: 100% of your fundraising dollars go back to the National Multiple Sclerosis Society. Have a blast and make a difference!

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 2 to 3 times more likely to get MS, and it affects over 2 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.
