RegisterWelcome to the Third Annual Great Marsh Mud Mosey which feature a 5Kish run throughout a very unique private property in Northern Chester County. The race proceeds will be donated to the Great Marsh Institute and ChesCo Search Dogs. The race and walk both start at 10:00 AM.
The Course
The course is relatively flat but will pass along through the marsh ponds on the property, alongside wooded boundaries past 100's of acres of farm land and then into the muddy portion of the property and then the last mile or so will be on a grassy surface to the finish line.

The race/walk is limited to the first 120 runners.
Post Race Activities
We will have the Epicurean Garage food truck for those looking to grab a bite to eat before they head home as well as beer and spirits will be supplied by Stable 12 Brewing and The Botanery Barn. We also have a DJ for some awesome tunes for the post race activities.
ChesCo Search Dogs will be performing demonstrations of their search dogs upon the completion of the race as well as we will have some Environmental Biologists that are willing to stay after the race and explain about the beautiful property and the very special animals and flora that you might have just passed on your race.

The Mud
While we cant promise a repeat of last years mudfest as mother nature was very generous with lots of spring rain. If you would like to take a glimpse of one of the muddier sections, feel free to watch a camera we had set up on the course. https://www.youtube.com/watch?v=UtttRnjwSHA
Pets
As this is a working farm (when races are not being held) and we will have the ChesCo Search Dogs on property, we ask that you do not bring your pets to the race.
