California International Marathon

Event overview

The California International Marathon (CIM) is a point-to-point, net-downhill marathon held on December 7, 2025, organized by the Sacramento Running Association, a 501(c)(3) nonprofit. The course starts in Folsom foothills and finishes at the California State Capitol in Sacramento. The route has a net elevation drop of 366 feet (111.5 meters), has remained unchanged for 42 years, and is certified and sanctioned by USATF. CIM is a Boston Marathon and U.S. Olympic Trials qualifier and the course falls within Boston Marathon Index standards, so it is not subject to index penalties or time adjustments. The event enforces a strict 6-hour course cutoff. The event also offers an In-Shape Fitness 2-person relay in addition to the marathon.

Registration and policies

Registration used multiple entry tiers with different flexibility: "Worry-Free Entry" (Gold) was deferrable and transferable, "Standard Entry" (Orange) was transferable but non-deferrable, and "Unprotected Entry" (Blue) was non-refundable, non-transferable, and non-deferrable. Entry prices listed included taxes and fees and varied by tier. The In-Shape Fitness CIM Relay required team captain registration and an access code to invite a teammate. At the time shown, all marathon entry levels, the relay, and late charity entries were sold out. The event policy states no refunds will be provided for any reason; transfers and deferrals depend on the registration type, and race organizers reserve the right to cancel for safety with refunds or credits not guaranteed.
