Hanna Boys Center changes the lives of troubled, motivated youth through faith, education and caring, helping them grow into productive members of society. Hanna is a “haven of hope” for troubled boys and their families. Our mission is to provide a “home away from home” for boys who are underprivileged, troubled, and seriously at-risk. We serve more than 100 boys at any given time, between ages 13 and 18, and we educate them in small classes from grades eight through twelve.

Hanna believes that every boy deserves to be treated with dignity and respect, to be empowered to fulfill their maximum potential and become contributing members of society. HBC provides over 100 volunteers both students and teachers for the amazing weekend events. Our partnership goes back to the very first Napa to Sonoma Wine Country Half Marathon in 2004.

Runners often have to dig deep and find some unnamed source of strength, perseverance, and determination. Finns have a name for that; it’s called “sisu”. Located in Sonoma, FAHA is a 501(c)(3) non-profit, residential and recreational cultural facility providing 48 subsidized and 16 moderate income apartments for qualified senior and disabled residents.

FAHA welcomes diversity and has an uncompromising commitment to and belief in inclusivity, providing housing regardless of culture, abilities, or ethnicity. Founded over 40 years ago by first-generation Finnish immigrants, today FAHA works to preserve its cultural heritage and build community under our name, Finnish American Home Association, through concerts, midsummer and harvest celebrations, and classes. You may meet FAHA volunteers at registration or along the course, but you are sure to find us after you cross the finish line as we’ll be ready to hand you your wine glass. Find some of your sisu at

Founded in 1875, the Native Sons of the Golden West is an organization with a rich history of historical preservation, which began in 1890 with the purchase of Sutter’s Fort when that landmark faced demolition and which continues to this day. The Native Sons was formed as a lasting monument to the men and women of Californiaӳ Gold Rush. Today the Native Sons of the Golden West maintain a strong sense of community building and help ensure a bright future through charitable endeavors and educational involvement. The Native Sons welcome members from all backgrounds who are California born. Native Sons contributes heavily to local non-profits, including the Cleft Palate Fund and the Historical Preservation Foundation, as well as encouraging and supporting local youth programs. They are the ones on the front lines for parking and traffic needs. They serve a crucial role in our races, so thank them as you pass by next year. Learn more at

The Napa Valley Vine Trail Coalition is a grass-roots nonprofit with a vision to build a walking/biking trail system to connect the entire Napa Valley–physically, artistically, and culturally. We are working to design, fund, construct, and maintain 47 safe and scenic miles of level, paved, family-friendly, pet-friendly, free-access Class I trail, stretching from Vallejo’s Ferry to Calistoga.

The Vine Trail provides many benefits for our community. It’s a proven model: Trails in residential and tourist areas around the United States have made an immediate positive impact on the well-being and safety of residents. A safe, free, easy-access trail system can significantly improve community health. Napa County has the highest rates of obesity and diabetes in the Bay Area. Studies show even moderate increases in physical activity reduce stress and risk of many serious health issues.

A continuous Vine Trail will connect Napa Valley communities, providing a car-free alternative for commuting and fun. This will reduce traffic congestion, taking cars off the road and pollution out of the air, significantly lowering our carbon footprint. The Vine Trail’s human scale, continuity, vast outdoor exhibition space, and easy access will unify the diverse landscapes and varied communities of this much-visited area physically, artistically, and culturally.

Altimira Middle School – Local middle schools are feeling the pinch financially so providing volunteers is a great way for them to fundraise, as well as do some team building. We love to support local school sports programs, and Altimira Middle School benefits from this opportunity by not only providing volunteers, but encouraging teamwork and camaraderie among classmates and teammates.
