It's time to get muddy, and we've got all the info you'll need to get ready for the big day!

Gates open at 9:00 am. You'll want to show up ONE HOUR prior to your running time on your registration confirmation to allow enough time for parking, bib-pickup or registration changes, etc. Event held rain or shine. Event director has the sole discretion to postpone the event in the case of severe weather. Check email and social media the morning of the event if weather appears to be a concern.

DOWNLOAD your required physical waiver above and bring it with you to the venue to pick up your running bib. Please fill out your waiver prior to arriving at the venue. PRINT a copy of your order confirmation email (or save it on your phone) for faster check-in. Bring your Photo I.D. along with your signed waiver to the registration tent.  A Parent / Guardian will pick up MF Kidz bib(s).

- PARKING Parking is $20 cash only 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-off accommodations are available inside the venue gate without charge. Parking is tight and you will be asked to follow the direction of the flaggers and parking attendants. If you have options for vehicles, we suggest leaving the large trucks and SUV's at home.

- 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 the tab on your running bib and attached it to your bag with a safety pin (available at the bag check table). Write the number down on your arm, as your bib may be lost during the run.

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 for 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. If you need additional hydration opportunities during your run, please bring your own water on the course.

Adult waves are a two lap system. You must cross the halfway point within 45 minutes to one hour after the last wave of the day (12:00 noon) takes off from the start chute. After this time, event staff may start to remove course markings and/or obstacles. Pace your first lap accordingly. If you think you need additional time to complete the full 5k, you should begin your run in an earlier wave time.

- WASH OFF STATION We will have a wash off area with running water.  Lines and wait times may be long. We suggest bringing a gallon or two of water and leave them on the roof of your car to warm in the sun, then rinse at your vehicle upon exiting the event. Bring a towel and a change of clothes.  Please take all unwanted items and trash with you, and do not leave a mess in the parking lot.
