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

TNT Raceway is just past Lubbock Dragway on your map. 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, registration, etc.  Event held rain or shine, though decisions regarding severe weather will be made by the event director as late as event morning. Check in with social media and email if in doubt.

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 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. Accommodations for drop-offs are available inside the venue gates 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 tab on your running bib and secure it to your bag with a safety pin (available at the bag check table). Write the number down on your arm with a sharpie, as your bib may be lost during the run. Watch were your bag is placed by the attendant for easier bag 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 $3 cash each.  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. While we are not a timed run, event staff starts to remove course markings after the halfway point between 45 minutes to one hour after the start of the last wave of the day and suggest you pace your first lap accordingly.

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