SAN FRANCISCO The FUN Mud Run Saturday, October 1, 2016

Price Increases in 13 days

MuckFest® MS is built for laughs and muddy from the get-go! Teams run in the same wave so you can experience all the muddy shenanigans, epic spills and thrills together. Re-live the adventure and celebrate your accomplishments with a free beer (or soda) in the MuckFestival. Spectators are free, and so is their front-row seat for the Start, Finish and several signature obstacles. Little ones can frolic in the free Lil’ Muckers play area.

We Muck It Because

We want to end MS. Even though the event is built for laughs from start to finish, we’re on a serious mission to advance cutting-edge research and support the life-changing work of the National MS Society.

The FUN mud run with the best obstacles! Our 5K course is built for laughs.

All you need are a pair of sneakers and a sense of humor to take on the obstacles on our truly muck-tacular 5K course. You’ll flip when you see it in person, but take a spin through the sample course below to get a taste of what you’re in for.
