Fueling & Hydration

The California International Marathon will have 17 aid stations spread throughout the course, each stocked with water (8oz. cups, ~5oz. liquid/cup) and Precision Hydration (8oz. cups, ~5oz. liquid/cup). Three of these stops will also be stocked with Precision Fuel gels and fruit.

Aid Station Information

Hydration tables are located on both sides of the road for Aid Stations 1, 2, and 3.

Hydration tables are located only on the right hand side of the road for Aid Stations 4 through 17.

At each hydration-only aid station, the first tables runners reach will have Precision Carb & Electrolyte Drink availabe, followed by water.

At each food and hydration aid station, the first tables runners reach will have Precision Fuel gels, chews, & bananas, followed by the hydration tables.

Medical services and portable toilets are located after the hydration tables on the right hand side of the road at all aid station locations.

NEW in 2026

The CIM course will feature three Self-Refill Water Stations, located at approximately mile 6.7, mile 14, and mile 20.5 along the course. These locations are approximately one quarter of a mile beyond Aid Station 3, Aid Station 7, and Aid Station 12. Self-Refill Water Stations give participants the opportunity to refill their own approved self-carried hydration gear with water only – no electrolyte mix is available at these stations. Participants will refill their own hydration gear within the station utilizing quick-fill spouts attached to a water tank.

Course and course services will be open to all runners that remain within the 6 hour finish cutoff pace. Sweep runners beginning as the final starters at 7:30am will mark the end of the race for course and finish line services. Any runners who fall behind the sweep runners will not be guaranteed any course or finish services (eg aid stations, medical services, finisher items, etc.). There will be sweep and drop out transportation provided at the back of the race and at the relay exchange zone to transport runners to the finish line as needed.
