You'll want to show up ONE HOUR prior to your registered wave time to allow enough time for parking, bib pickup or registration changes, etc.  Event held rain or shine, with possible postponement exceptions due to severe weather. Check social media and email the morning of the event if weather appears to be a problem.

- PARKING Parking is $20 cash per vehicle. You must park in our designated parking area only. No parking on streets, roads, or adjacent lots allowed. Absolutely no "walk-ins" from outside the designated event parking area will be permitted to participate in any Mud Factor event, no exceptions. Drop offs are permitted inside the venue without charge. You will be directed by staff where to park your vehicle. Please be careful when opening doors around other vehicles.

- BAG CHECK You may drop off any items you don't want getting muddy or lost at our Bag Check tent for $5 cash. Tear off tab on bib and attach with safety pin at table, write your number down on your body with a sharpie pen, and pay attention where the attendant tells you where your bag is placed.

You may purchase or pick up your pre-ordered merchandise at the merchandise tent located in the festival area.  You MUST pick up pre-ordered shirts on event day. We do not ship, refund, or credit pre-paid merchandise.

We recommend bringing extra clothes, shoes, and towels. Bring plastic bags for dirty items. We have plastic car seat covers for sale at the merchandise booth.  Bring water to hydrate before and after your run.  Mud Factor provides water at the 1.6 and 3.2 mile mark to help quench your thirst. Please take only one cup per pass and do not use the drinking water as a rinse station. Bring your own water on your run if you think you'll need it at more frequent intervals. Please throw away cups or bottles properly.

- WASH OFF STATION We will have a wash off area with running water, but lines can get long and crowded. We suggest bringing a few gallons of water and leaving them on the roof of your car to warm in the sun, then rinse at your vehicle.   Bring a towel and a change of clothes.  Please take all items with you, and do not leave a mess in the parking lot.

We will have a local food vendor in the festival area, please support them. Clean up after yourself.
