About the Event

Muddy Dash is not your average mud run! Get ready for up to 3 Miles of messy mayhem. You and your friends/family can expect to run, walk, crawl, wade, slip, slide, and scream with excitement as Muddy Dash gets you fabulously filthy. We’re consistently striving for innovation and excitement in our obstacles, so there’s always a chance you’ll see something brand new! From the moment you step off of that start line, until you triumphantly cross the finish, we hope you’re prepared to have the time of your life among so many of your new best friends in the Muddy Dash community.

Choose your start time and run with your friends and hundreds of others on this obstacle course!

Get more details on our website so you're ready to conquer YOUR Muddy Dash!
