Event Day Info - Denver, CO

- SHOWING UP
Gates open at 9:00 am. You'll want to show up ONE HOUR prior to the wave time you signed up for to allow enough time for parking, bib pick-up or registration, transfers, etc. Event held rain or shine with postponement exceptions for severe weather (lightning storms, tornado warnings, flash flooding, etc).

- BIB PICKUP
DOWNLOAD your required waiver above prior to coming to 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). Don't have a printer? Print at work, ask a friend, neighbor, or another member of your running party to bring you one.

- 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 gate 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. Grab a safety pin from the table and tear off the numbered bag check ticket off your running bib and attach it to your bag. Write the number on your arm with a sharpie as a reminder, as you may lose your bib on the course. Ask the runner what line they are placing your bag in for easier 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 pre-paid merchandise.

- COME PREPARED
We recommend bringing extra clothes, shoes, and towels. Wear sunscreen. Bring plastic bags for dirty items. We have plastic car seat covers for sale at the merchandise tent. Bring ice cold 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. Bring water on your run if you think you will need it at earlier intervals. Please use only one cup per pass and do not use the drinking water as a rinse station for your body. Please dispose of cups and bottles properly and do not litter on the course.

NOTE: Adult waves are a two lap system. You must pass the halfway point (1.6 miles) within 45 minutes to one hour after the last wave of the day (11:30 am) 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.
