The California International Marathon point-to-point, the net downhill course has remained unchanged since its first edition in 1982. It provides over 100,000 runners of all speeds – from first-timers to the fastest of the fast–the best chance to achieve their marathon goals. The course is USATF certified.

Not yet ready for the full 26.2-mile marathon distance but still want to take part in the CIM fun? Round up some friends and form a team for the CIM Relay Challenge! CIM Relay Challenge teams can be 2, 3, or 4 runners, and together teams complete the full marathon distance with each runner completing a leg of 5.9-7.5 miles (distances vary on each leg). And who knows . . . this year’s relay runner may be next year’s marathon finisher!
