Thank You for an awesome 2014 event!

A special message from the Northern California Chapter of the National MS Society. Thank you to all the 2014 runners, volunteers and staff who came out to run, help and support each other at this year's event. All of you helped make the 2014 MuckFest MS San Francisco a great success. Every day of the year, we work hard to support people living with multiple sclerosis; after all that’s what we are here for. Remember, 100% of the funds you raise support the MS Society and the 14,000 people living with MS in the region. There is still time to support the mission behind the “muck” and help us reach our fundraising goal by making a $10 donation. Make a donation online at Every $10 raised will help us get one step closer to a world free of MS.
