Frequently Asked Questions
If you have a question click here and see if we have an answer for your question.
You need to arrive an hour BEFORE your muddy, foamy, wave starts to allow enough time to get registered, scope out the mud, and soak in the awesome atmosphere. If you are one of those chronically late people, tell yourself you need to be there 2 hours early.
What to bring
First off bring your friends and family—or anyone else who needs proof of your mud run and obstacle course skills or someone who needs a demonstration of your mud flinging abilities. Don't forget your mud money for parking and fun! You should probably bring a towel and some extra clothes because your clothes will get muddy and wet, but you probably already guessed this. If you forget your game face, then you're FOL (Foam Outta Luck).

Also, please bring your signed and printed waiver (as well as signed and printed waivers for any teammates' bibs you're picking up) to packet pickup!  We cannot release bibs without a signed waiverfor each participant.  There is a charge for replacements at bib pickup if you forget! (If you've lost your waiver, you can download a new one on the race location information page by scrolling down to where it says "waiver" and clicking the link.) 
Make sure to bring a copy of the waiver signed by you to the race. If you dont have a copy of the waiverclick here to download it and then print it off and sign it. If you do not bring the waiver, it will be $1 day of race to receive the waiver.
BIB Pickup

Gear Check In
Try and leave as much stuff as you can at home or in your car— but for the stuff you can't leave behind, or that you don't want covered in mud and foam, we will have a secure place to check in your gear. Please note that we do not accept children at the gear check-in.
What to wear?
We said "Adventure Run" right? Well folks let's get adventurous! Anything goes as long as you wear some clothes. You will be running in foam, mud and water so you'll want something that can get muddy, foamy and that allows you the freedom to move and groove. Costumes are the coolest and come with their own list of pros, so choose but choose wisely my friends.
What do I get?
For starters, yes, you will be getting so much more than the already rad 5K Foam Fest FREE Race T-shirt. You get the chance to win prizes. Also, take advantage of our nearly endless supply of FREE (temporary) tattoos—so you can get all tatted up for the day. Ace in the hole, and then a GOOOOOOAAAALLLLL!!!!!!!! ! Not to mention of you finish the run you get the coveted Foam Fest medal. While partying with us, you get FREE access to Games and Activities like: Foam Pit, Pull-Up Bar, Mud, Limbo, Minute to Win It games, etc. etc. And to top it all off you get a free cold one on us. That's right if you're over 21 the first drinks on us, so make sure you bring your ID to prove it (not available in all states).

Special Bonus! Included in your registration is a one year subscription to a magazine of your choice-a $20 value! Select from: Men's Health, Women's Health, Bicycling or Prevention. Details on how to claim your subscription or request a refund will be found in your Virtual Race Bag. 
It's only fun if you do it in style and with a group and yes we're talking about parking. So carpool if you can. Parking is $10 per vehicle.
When you're the type that works hard, plays hard and parties harder—you need a place where you can get some serious rest.
