The Lowdown

The California International Marathon runs point to point from Folsom Dam to the California State Capitol in Sacramento. The start is at about 366 feet above sea level and the finish at about 26 feet. The first half rolls through the suburbs east of the city, and the second half is flat. The course is certified and a Boston qualifier. In 2025, 8,178 runners finished, and 30.2 percent of them ran a Boston-qualifying time. John Mansoor and Sally Edwards founded the race. Mansoor based the course on his own training run from Folsom Dam into Sacramento. The first edition was run on December 4, 1983, with about 1,600 starters. From the start it paid men and women equal prize money. The Sacramento Running Association organizes it. CIM was the U.S. national marathon championship for men in 1984 and for women in 1984, 1985, 1989 and 1993. It hosts the USATF Marathon Championships in 2025 and 2026. Tsegay Weldlibanos set the men's course record of 2:07:35 in 2024, breaking a mark that had stood for more than 20 years. The race is held in early December, on the second Sunday after Thanksgiving.

May 20, 2026: Sutter Health Announced as Presenting Sponsor

Dec 7, 2025: Course Records Broken at the 2025 USATF Marathon Championships
The 2025 California International Marathon, held as the USATF Marathon Championships, saw new course records: a women's course record in a marathon debut and a men's American-course-record performance, plus a masters women's course record and a masters men's record among roughly 8,200 finishers.

01: The California International Marathon (CIM) is a point-to-point, net downhill course from the Folsom area to the State Capitol in downtown Sacramento, which makes it one of the nation’s fastest marathon courses and a high producer of Boston qualifiers.
02: Finishers receive a custom finisher medal and a technical long-sleeve shirt, with post-race food, recovery areas, and a beer garden for participants and spectators near the finish line.
03: Race weekend typically includes a runners’ expo with packet pick-up and vendors, a Saturday pasta dinner (ticketed), and a kids’ fun run to engage families and supporters.
04: Aid stations are well-spaced approximately every 1.5–2.5 miles offering water, electrolyte drink, and gels at select stops—plan to carry your own fuel if you have specialized needs.
05: Transportation and parking are limited near the start in Folsom, so most runners use shuttle buses to the start or arrange drop-off; layers are recommended for the cool December morning with warmer conditions possible in the afternoon.
