The course is partially on the road and partially on trails and includes hills, water (no contact with lake anywhere), professionally built obstacles and over a dozen mud pits. You asked for even more mud, you got it! You will get wet and you will get muddy. Be sure to bring towels and a change of clothing. COURSE MAP: To view the course map from prior events, click HERE. We update  the course for each event and will post the new course map a week or two prior to the event, as we add and build new obstacles and keep changing the course up to keep it fresh and with new surprises!

Individual and Team Competition

Participants may compete as individuals or as part of an open sized team with an unlimited number of runners. Costumes and matching team outfits are encouraged.  Help us make this the wildest mud run ever. Award categories include: * Individual Male * Individual Female Age brackets are standard five year increments. Choose your age upon registration. You must be 13 years of age or older and in good health to participate in the adults mud run. Kids 12 and below are allowed to REGISTER and run in the Mud Puddles Kids Race Area.

Wave Start

The start will consist of separate “waves”. The first wave will be individual timed runners at 9:00am. Then timed teams at 10:00am, then untimed individuals at 11:00am, untimed teams at noon, and then the kids run at 1:00pm. Waves times will be added to meet demands of registration patterns in the afternoon after the kids run. Timed waves will be further subdivided and sent off in 3-5 minute waves due to the narrowness of the trails in several areas and flow of participants over the obstacles. This will help prevent crowding, and as a result some waves will fill up and no longer be able to be registered into. Winning times for timed runners and teams will be based on TAG time, not GUN time, so it is possible for individual runners in the second and later waves to place in the event.


Awards will be given to the top 3 male and female individual finishers in each 5 year age group for timed individuals only. There are no awards for teams. All age group awards must be picked up on the day of the event. There will not be an awards presentation so once the results are posted you can pick up the medal from the volunteer booth near the finish line.

Entry Fees

Non-refundable and non-transferable. Once we accept your entry, you will not receive a refund if you cannot participate. You may not give or sell your number to anyone else.


Online and mail in entries will be confirmed by e-mail if a valid email address is provided. If you mail in your entry, your canceled check is your receipt. If you do not receive an email confirmation it may be due to spam filters or firewalls on your computer, so please check these if you have not received your confirmation.

Packet Pick Up

You will be given the choice to have your packet mailed to you, or to pick it up same day on site at the event for an additional charge. As we have thousands of participants it is logistically impossible to hand out all race numbers and t-shirts the day of the event, thus we have packet pick up the day before the event at no charge. This will be on Friday, the day before the Mud Run at Road Runner Sports in Costa Mesa, located at 1835 Newport Blvd Ste A101, Costa Mesa, CA 92627  from Noon-7:00pm
