The California International Marathon (CIM) is one of the most iconic marathons in the U.S., known for its net downhill course and perfect blend of elite racing and runner-friendly organization. From its meticulously planned logistics to its enthusiastic community support, this race offers an experience that draws both first-time marathoners and seasoned runners chasing personal records or Boston Qualifiers (BQs). Held annually in Sacramento, California, CIM promises a race day you won’t forget.

Why You’ll Love the California International Marathon

• A Fast and Scenic Course: The point-to-point course begins in Folsom and runs through suburban and urban Sacramento, culminating with a dramatic finish at the State Capitol. While billed as “net downhill,” runners should prepare for rolling hills in the first 20 miles that add variety without being overly challenging. The final 10K is flat, offering a great opportunity to pick up the pace and push to the finish.

• Elite-Level Organization: CIM is famously “for runners, by runners,” and the attention to detail shows. Aid stations every 1-2 miles are stocked with water, Nuun, and Gu gels, ensuring you stay fueled throughout the race. The race’s porta-potty-to-runner ratio is among the best, making pre-race and on-course stops stress-free. Shuttle buses to the start and back from the finish are well-organized, ensuring a seamless transportation experience.

• Perfect Weather for Running: Sacramento in December offers ideal marathon conditions. With temperatures typically ranging from the mid-40s at the start to mid-50s at the finish, you’ll enjoy a cool, comfortable race. Occasional fog in the early miles adds a touch of drama to the morning.

• Incredible Post-Race Swag: Runners rave about CIM’s finisher swag. From reusable water bottles to stylish backpacks and commemorative jackets, the race goes above and beyond to ensure participants leave with meaningful mementos. The finisher medal, often inspired by the California state flag, is a favorite among runners.

• A Chance to Qualify for Boston: CIM is known as a “fast” course, consistently ranking as one of the top races for Boston Marathon qualifiers. The combination of rolling hills, downhill stretches, and strong crowd energy creates the perfect environment for achieving your goals.

What You Should Know Before You Go

• Prepare for Rolling Hills: While the course is net downhill, the rolling hills in the first 20 miles can be challenging if you’re not prepared. Incorporate hill training into your preparation to ensure a strong performance.

• Arrive Early for the Start: With thousands of runners, the start line can feel crowded. The shuttle system is efficient, but it’s best to arrive early to avoid stress. Expect some lines for porta-potties and be ready to warm up on the go.

• Support for Slower Finishers: CIM enforces a 6-hour course limit. While some support remains for slower runners, finish-line amenities may be scaled back toward the end. Bring a hydration bottle and extra nutrition if you anticipate a longer finish time.

• Scenic but Suburban: The suburban and urban stretches of the course are functional rather than picturesque. However, the finish at the State Capitol and the energy from spectators more than make up for it.

The California International Marathon is a race that combines the prestige of elite competition with the welcoming atmosphere of a community-focused event. Whether you’re chasing a personal best, qualifying for Boston, or simply soaking in the spirit of a well-loved marathon, CIM offers an exceptional experience from start to finish.
