Welcome to the 2026 California International Marathon.
CIM strives to offer multiple registration options that provide registrants maximum flexibility in their marathon race entry. Each marathon entry tier and price point offers different registration solutions if you decide at any time you are unable to run the marathon. These options range from NO flexibility in our "Unprotected Entry" (Blue) level all the way to a fully transferrable or deferrable option in our "Worry-Free Entry" (Gold) level.
Please review each level before purchasing.
Please Note: CIM has a strict 6-hour course cutoff
Due to unprecedented demand, all three of our standard registration tiers (Blue, Orange, and Gold) sold out at record speed. In response, we are releasing an additional LIMITED amount of Marathon “Worry-Free” (Gold) entries, available through two special opportunities:
Option 1 (Apply & Wait): Apply for the CIM Gold Entry Draw before May 1st
Option 2 (Buy Now): Secure a Gold Entry now with a Mandatory Charity Donation
