Welcome to the Great Marsh Mud Mosey

The Third Annual Great Marsh Mud Mosey features 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

  • Layout: The course is relatively flat but will pass through marsh ponds on the property, alongside wooded boundaries past hundreds of acres of farmland.
  • Muddy Sections: Participants will encounter the muddy portion of the property before transitioning to a grassy surface towards the finish line.
  • Limited Participants: The race/walk is limited to the first 120 runners.
  • Course Flyover: Click on the link for a flyover of the course. View Flyover

Post Race Activities

  • Food: Enjoy pulled pork for sandwiches or platters, and pizza from on-site ovens.
  • Beverages: Beer and spirits will be supplied by Stable 12 Brewing, Victory Beer, and Big Rack Spirits.
  • Entertainment: A DJ will provide music for the post-race activities.
  • Demonstrations: ChesCo Search Dogs will perform demonstrations of their search dogs after the race.

Educational Opportunities

  • Environmental Insights: Environmental Biologists will be available to discuss the flora and fauna of the property.
  • ChesCo Search Dogs: To learn more about ChesCo Search Dogs, please visit their website.
  • Great Marsh Institute: To learn more about The Great Marsh Institute, please visit their website.

The Mud

While we can't promise a repeat of last year's mudfest, 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 Video

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

This is a rain or shine event! Remember to dress for the event! It's called the Mud Mosey for a reason. Almost guaranteed to get Muddy! Please check this space for updates in case of inclement weather conditions.

Refund Policy

Kindly note that all registration fees are non-refundable but check with your tax consultant, should be tax deductible.

Parking and Driving On-Site

Once you enter the property, follow all signs for parking. Please drive carefully as this is a narrow and gravel road, keeping your speed under 25 MPH to avoid damaging the road and your vehicle.
