Great Marsh Mud Mosey

Welcome to the Great Marsh Mud Mosey

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

• Terrain: 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.
• View the Route: Click on the link for a flyover of the course. Flyover Link
• Capacity: The race/walk is limited to the first 120 runners.

Post Race Activities

• Food Truck: We will have the Epicurean Garage food truck for those looking to grab a bite to eat before they head home.
• Beverages: Beer and spirits will be supplied by Stable 12 Brewing and Victory Brewing and Botanery Barn.
• Entertainment: We also have a DJ for some awesome tunes for the post-race activities.

The Mud

While we can't promise a repeat of last year's 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. Watch Here.

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.

Gear Check
