Race Details

Please join us for the 2nd Annual Moose Mudder! This is a community event that will consist of an untimed 1k fun walk/run and a timed 5k followed by an optional muddy obstacle course. Get your best time, run for fun, walk with a group, or form a stroller brigade--Come one, come all as we gather and play as a community on Sunday, May 3rd at 8am! Local businesses will be there in full force as well as food trucks--you won't want to miss it!

Look for a table at the Marvelous Moose Showcase on April 30th from 5:30pm to 7:30pm to pick up your race packs. This will help avoid long lines the day of the event.

Upon arriving, check in at the registration table if you didn't already pick up your race bib, t-shirt, and moose antlers at the showcase . If you haven't already registered, you may do so the day of; however, the price increases to $30 and will not include a t-shirt or moose antlers.

Mr. Schleich and Mr. Mundy made muddy obstacles that are optional after finishing, so have your cameras ready or stop by the selfie photo booth! And, don't worry because they made a shower too!

If you're wondering what to do with your muddy shoes, bring a clean pair with you and leave your muddy shoes at the One World Running drop off zone. This organization will clean the shoes and deliver them to runners in need around the world! Last year we donated five LARGE bags!

The school will be open for restroom use, but please help us to keep it clean and mud-free.

A special thanks to all of our sponsors for helping to make this event possible! You can thank some of them personally by visiting their pop-up tents--I bet you'll find some goodies and snacks there too!

The official Moose Mudder '20 logo was created by your very own Mr. Hay!
