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

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.
