REMEMBER: Parking is free, but we strongly ask that you carpool and bring a food donation for Operation Food Search.
(Plus you’ll receive a raffle ticket to win awesome prizes just for donating!)
  1. Download Your Digital Packet
    This year, we do NOT have a physical packet to pickup prior to the race. You will receive your bib and electronic timing chip at registration at the race. (**Please note, you will be responsible for turning in your timing chip wristband after the race.) However, please download this digital packet that includes a checklist, a course map and messages from our sponsors.

  2. Arrival Time
    On Saturday 5/21, please arrive 60 to 90 minutes before your wave time. Please note, there will be heavy construction on I-70. If you do not remember your wave time, then review your email from Eventbrite because your wave time and The Battlegrounds’ start time are listed separately on your email. Your wave time is listed below the event’s start time further down on the email (underneath the parking FAQ).
  3. What To Bring:
    1. Combat – Put your game face on, grab your gear, and get ready to get down and dirty…really dirty! Really REALLY dirty!!
    2. Creds – Identification to sign in (and prove you’re 21 and older for that free post-race beer) plus to complete a waiver release so you can battle with your friends!
    3. Carpool – We’re looking at a minimum of 3,000 racers – and 1,000+ spectators – so parking is going to be tight. We love carpoolers!
    4. Cans – For every canned good you bring (it all goes to Operation Food Search to feed St. Louis’ hungry), receive a raffle ticket for a chance to win some amazing prizes. Feel great giving…and receiving!
    5. Choos – Muddy shoes, that is. Leave ‘em with us so they can be donated to the needy in developing nations (proceeds benefit Operation Food Search.)
    6. Clothes – Bring extra clothes, clean up at our on-site showers, and then walk to our nearby Cedar Lake Cellars winery for an after-battle break.
    7. Chums – For your friends who just couldn’t commit to the race-of-a-lifetime, we offer free spectator admission. Other freebies: parking, gear check, festival area, and free kids’ mud zone for those 12 and under.
    8. Cash – For food, drink, Battle swag, and our Hero Alley post-race challenge (participation is free, but donations to Operation Food Search are greatly appreciated.)

  8. HAVE FUN!!

8 a.m. 5-Mile Elite Wave Runners (EWR)

  • EWR will be wearing bib numbers 1–199.
  • Check in at the Elite Wave registration line for your bib, timing wrist band, and a wrist band with you bib number on it.
  • After you register find a “marker volunteer” and get your bib number written on your head and any other exposed skin areas.
  • EWR must complete all obstacles. If you don’t complete the obstacle on your first time you can try again, but will need to get in the back of any lines waiting for that obstacle before you try again. At the Gauntlet you can pick any lane you want to.
  • Failure to complete an obstacle or cutting the course will result in disqualification, but you will still be timed.
