Modesto Marathon routes


Runners travel from downtown to the historic, tree-lined college neighborhoods. After passing the Modesto Junior College west campus, they head into the countryside viewing the beautiful Diablo Mountain Range and passing the San Joaquin River National Wildlife Refuge.

Runners then make their way back toward town, finishing near the start line.

The flat, fast course will be open 7 hours, allowing adequate time for first-time marathoners.


Runners will travel through tree-lined historic college neighborhoods, past Modesto Junior College’s west campus, and into the countryside surrounded by scenic orchards.

The 3.1-mile loop begins at 7:25 a.m., 25 minutes after the marathon runners.
