Our festival zone and parking will be in the back lots of Myers Park off Hwy 168.   Parking may change to a rain contingency plan at Myers Park Expo parking lots the week of the event if there is inclement weather.

- 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 tab on your running bib and attach it to your bag with a safety pin (available at the bag check counter). Write your bib number on your arm with a sharpie pen, as your bib may be lost on the course. Pay attention to wear your bag is placed for easier retrieval at pick-up.

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.  If you think you need hydration before the 1.6 mile mark, bring water 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.  If you are running in the last few waves, you must pass the halfway point (1.6 miles) within 45 minutes to one hour after the last wave of the day leaves the start chute. Please pace your first lap accordingly as staff may start removing course markings after this cut-off time. If you think you need additional time to complete the course, consider changing to an earlier start time.
