Anaheim Semper 5K & 10K Run

May 15, 2021 Anaheim, CA US 92807 Directions
It is with the deepest regret....

New Date: May 15, 2021

We are announcing the cancellation of  the 7th Annual Semper 5K & 10K which was originally scheduled for May 16, 2020.
This difficult decision comes after numerous conversations with the City of Anaheim, the County of Orange, prospective sponsors and so many others who were involved in the planning of this event.  In order for us to put on the first class event that our participants have come to look forward to and that we want to provide to you, we would need more time than what the city can provide during this crisis. 
The cancellation of this event was an extremely painful decision for the Committee to make, especially since this is our one and only fundraiser in support of the Marines, Sailors and families of the 13th MEU.  We hope to see all of you next year.
Thank you for your patience and understanding,
Anaheim 13th Marine Expeditionary Unit Adoption Committee
