COMPETITIVE TEAMS!! Teams that feel they will complete this event in under 47 minutes, you may request an early start time after you have registered by sending us an email to info@eggplantevents.com and providing us with a finish time from a previous USMC Mud Run or another Mud Run of similar distance. This information will be verified, and we will do our best to advance your start time if a team drops out of the event.

Once you are registered, all you will need to do is check in ONE HOUR prior to your Start Time and bring your signed Participant Waiver. Please click here to download a Waiver. This form must be turned in at the event, not before! You will need one waiver per participant. If a participant is under the age of 18 AND a parent or legal guardian will not be present at the event, a parent or legal guardian must sign the waiver and have it notarized prior to the event and the participant must bring it with them. This does not include JROTC participants however it does include all Pollywog participants.
