Summer of Mud Packet Pickup

Irvine Lake Mud Run – Summer of Mud Packet Pick Up Info

For those of you that did not choose to pay for the “mail my packet/race bib to me” option, below you will find important details (date, time, location address) regarding packet/bib pick up. Note that we are dedicated to making sure the packet/bib pick up experience goes as quickly and efficiently as possible.

Packet pick up will be on Friday, the day before the event, at Road Runner Sports. We will only be at ONE store for this event. All participants MUST pick up their Race Numbers (bibs) and T-shirts. There will be NO RACE DAY PICK UP AVAILABLE unless that option was chosen and the convenience fee paid.

With thousands of participants it is not logistically possible to take care of this all on event day, thus we dedicate a full day for this process which makes event/race day so much smoother. As we understand not everyone is able to make it to the pre event packet pick ups, we do offer the mail back and same day options for a nominal fee which in most cases is a fraction of the gas money and time that it would take for out of area participants to come to the expo location. Thanks for your understanding.

Additionally, Road Runner Sports is offering a 10% discount (20% if VIP) to all participants for any purchases made in the store that day.


Pick up;

Friday, Day before the Mud Run, noon-7pm

Road Runner Sports Costa Mesa

Costa Mesa, CA 92627

The store is located in the Costa Mesa Courtyards shopping center and additional parking can be found across the street in the Triangle Square parking garage.

Please do not call the store with questions about the Mud Run as there is no Mud Run staff at the stores prior to the packet pick up day. For questions or concerns email . Also please read the FAQ’s and General info as they will answer 99% of the questions. Most emails are answered within the same day or 24 hrs.
