Modesto Marathon

2026 here we come! The Grafitti Classic Car theme will be back again with more cars and more entertainment. Visit our website for event details. Our Cause Proceeds benefit the Teens Run Modesto program, which challenges area youth, especially those at-risk, to experience the benefits of goal-setting, character development, adult mentoring, and improved physical fitness through a structured training program culminating in the running and completion of the Modesto Marathon.
