About the Rotary Mission Ten Half Marathon

The Rotary Mission Ten Half Marathon is held in late January in San Juan Bautista, California, about 50 miles south of San Jose. The USATF-certified course starts and finishes in front of Mission San Juan Bautista and runs through farmland on rural roads, passing Anzar Lake and climbing into the Anzar hills. A 10 Mile, a 5K and a kids 1 mile fun run start the same morning, and the Rotary Club of Hollister puts proceeds toward local scholarships and charities. The 2027 race is the 43rd edition.
