- RUNING BIB PICK-UPPRINT the required waiver at home and bring or show a copy of your order confirmation email for faster check-in. Bring your Photo I.D. along with a physical copy of your signed waiver to the registration tent.  A Parent / Guardian will pick up MF Kidz running bibs.  bib(s). Do not enter the registration line without a signed waiver already filled out. You will not be allowed to participate without presenting a physical copy of your signed waiver. Don't have a printer? Print at work, find a friend, or visit a copy center prior to the event. We have a large volume of runners to process in a very short window of time, and holding up the line while you fill out required legal documents slows down that process tremendously

Secure the bag check tab on your running bib to your bag with a safety pin (provided at the bag check table), and write the number down on your body with a sharpie as your bib may become lost during the run. Watch where your bag is placed for easier retrieval at pickup.

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 tent to protect the interior of your vehicle if you find it necessary.  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, dispose of your trash properly, and do not use the drinking water as a rinse station. If you require more frequent hydration opportunities, please bring your own water on the course.

Mud Factor Adult Waves are a two lap system. You must cross the half way point within 45 minutes to one hour after the last wave has left the start chute, as staff will start to remove course markings at that time. Pace your first lap accordingly and if you feel you will need additional time, we suggest switching to an earlier wave spot.
