The Fastest Course in the West. The California International Marathon (CIM) is a marathon organized by runners, for runners!

The point-to-point, net downhill course has remained unchanged for 38 years, providing over 100,000 runners of all speeds–from first-timers to the fastest of the fast–the best chance to achieve their marathon goals.

CIM is certified and sanctioned by USATF and is a Boston Marathon and US Olympic Trials Marathon qualifier and is put on by the Sacramento Running Association.
