2026 California International Marathon

Experience the exhilarating 2026 California International Marathon (CIM), where runners from around the globe gather under the golden sun of California. Set along picturesque coastal roads, this marathon offers breathtaking scenery and a vibrant atmosphere that makes every step count.
The race course is designed to challenge both seasoned athletes and newcomers alike, winding through scenic neighborhoods before opening up onto expansive ocean vistas. The route ensures a mix of urban charm and natural beauty, making it a perfect destination for runners seeking an unforgettable experience.
CIM provides multiple registration options tailored to meet the needs of every runner:
- Worry-Free Entry ($230 + tax): Enjoy full flexibility with this option, allowing you to defer your entry to 2027 or transfer it to another participant in a 2026 CIM Relay race. If transferring to an individual, ensure they are signed up for the same marathon.
- Standard Entry ($200 + tax): This tier offers some flexibility by allowing transfers to other races within the 2026 series but is non-deferrable and non-refundable once registered.
- Unprotected Entry ($180 + tax): The most straightforward option, this entry level does not offer refunds or deferrals.
For those who have already secured their place in previous years through a deferral code, you'll find instructions on how to use it. Deferral codes were sent via email as of December 16, 2025; make sure to check your inbox for details.
Additionally, the CIM Relay team registration opens later this year, offering another exciting way to participate in the marathon experience with friends or family.
The race maintains a strict 6-hour course cutoff time. While there are no refunds provided due to personal circumstances such as injuries or travel delays, transfers and deferrals may be possible under certain conditions specified during purchase.
In case of any changes to event details like start times, transportation, or amenities, participants should be prepared for potential modifications but will not receive a refund unless the race is canceled. In such an unfortunate scenario, organizers might offer alternative registration options as compensation.
Join us at CIM and immerse yourself in a community that celebrates endurance, resilience, and the sheer joy of running under California's brilliant skies.
