Welcome 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.

Post Race Activities We will be changing it up this year and we will be preparing pulled pork for sandwiches or platters raised right on the farm by our on site professional chef for those looking to grab a bite to eat before they head home and pizza made from the pizza ovens right near the barns as well as beer and spirits will be supplied by Stable 12 Brewing and Big Rack Spirits . 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.
