Marathon Registration Solutions
December 7, 2025
Welcome to the 2025 California International Marathon
CIM strives to offer flexible registration options to meet the diverse needs of our participants. Each marathon entry tier is designed to provide a different level of flexibility — from no flexibility in our “Unprotected Entry” (Blue) level to full transfer and deferral options in our “Worry-Free Entry” (Gold) level — empowering runners to choose the option that best fits their needs.
Please note: All regular marathon entry tiers (“Unprotected Entry” Blue, “Standard Entry” Orange, and “Worry-Free Entry” Gold, as well as the Marathon Late Entries “Supporting Local Non-Profit Programs”, for the 2025 California International Marathon are now sold out.
Registration for the 2026 California International Marathon will open after the December 7, 2025 race.
If you are looking to participate in 2025 by securing a transfer bib or joining a relay team, you may do so through our Relay Friend Finder and Marathon Transfer Message Board. If you are a 2025 current participant with an Orange, Gold, or Late Entry and want more information one transfers and deferrals you can read more here.
****Please Note: Due to course limitations we ask that you respect our six hour marathon time cut-off. Race organizers can not guarantee runner services after the 6 hour mark. This includes: course support, fluids, nutrition, official finisher items such as the finisher medal, or official results.****

Marathon “Late Entry” (Supporting Non-Profit Programs) $380 SOLD OUT
CIM’s Marathon Late Entries that benefit local non-profit programs will be offered after the marathon sells out of all 3 registration tiers. Late Entries will have the same registration solution options as the Marathon “Worry-Free Entry” (Gold) tier, as it will be transferable or deferrable. If you are unable to run the 2025 marathon, the “Late Entries” (Supporting Charity) will allow you to transfer your bib to the 2025 relay OR transfer your 2025 marathon bib to another runner, OR defer your marathon entry to the 2026 CIM. If you transfer your Late Entry to another runner, your race entry fee ($230) will be refunded, but the donation portion ($150) of the entry is non-refundable.
Marathon “Worry-Free Entry” (Gold) $230 – SOLD OUT
The marathon Gold level entry provides the most security in your marathon registration. If you are unable to run the 2025 marathon, this “worry-free” entry will allow you to transfer your bib to the 2025 relay OR transfer your 2025 marathon bib to another runner, OR defer your marathon entry to the 2026 CIM. The marathon Gold entry is non-refundable (unless successfully transferred to another runner), but it DOES allow you to either run, transfer, or defer.
Marathon “Standard Entry” (Orange) $200 – SOLD OUT
The marathon Orange entry is our standard price option for the 2025 marathon. If you are not able to run the marathon distance, the standard marathon entry will allow you to transfer down to the relay or allow you to transfer your marathon bib to another marathon runner looking for a bib and receive a refund. The marathon Orange entry is non-deferrable and non-refundable (unless successfully transferred to another runner). You must run or transfer in 2025.
Marathon “Unprotected Entry” (Blue) $180 – SOLD OUT
This unprotected marathon entry provides the lowest price to secure a spot in the 2025 Marathon. The marathon Blue entry is non-transferable, non-deferrable, and non-refundable. Please note that this registration option has no additional safety net, it is the lowest price, but puts you at risk for no registration solution options. You must run the marathon in 2025, and there is no registration solution option available if you are unable to run.
