Mud Factor Event Day Info ST LOUIS

- SHOWING UP
Gates open at 9:00 am. You'll want to show up ONE HOUR prior to your wave time to allow enough time for parking, bib pick-up, registration changes, etc. Event held rain or shine, with the possible exception for postponement at the discretion of the event director for severe weather. Check email and social media the morning of if severe weather appears to be an issue.

- BIB PICK UP
PRINT 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 your signed waiver to the registration tent. A Parent / Guardian will pick up MF Kidz 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.

Can't find your confirmation? CLICK HERE to enter the email address affiliated with your registration purchase and it will be resent to you.

- 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. There are accommodations for drop offs inside the venue without charge.

- 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 bag check tag on your running bib and secure it to your bag with a safety pin (available at the bag check table). Write your number on your body with a sharpie pen, as your bib may be lost on the run. Watch which line your bag is placed in for easier bag retrieval.

- MERCHANDISE
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.

- COME PREPARED
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 in the festival zone to protect your vehicle interio. 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. If you need additional hydration during your run, please bring what you need with you on the course. Please take only one cup per pass and do not use the drinking water as a rinse station.

Mud Factor adult waves are a two lap system. You must pass the half way point within 45 minutes to one hour after the last adult wave has taken off from the start line, as course markings may start to be removed at that time. If you feel you need additional time to complete the full course, we recommend you begin your run in the earlier time slots.
