Official Charity Partners

Need a guaranteed entry into the race?  Interested in fundraising for a charity? We offer a few options to support worthy organizations throughout the country. With a minimum donation of financial support (varies by charity), you’ll receive a race entry to the Napa Valley Marathon and Half Marathon event and, in some cases, online training and/or other benefits from the charity including the camaraderie and special feeling of helping others.

Keep scrolling to learn more about our 2024 charity partners. If you are interested in signing up with one of our charities, follow the link provided for your charity of interest. If possible, look to a charity that has meaning for you, whether in memory of a family member, to support a friend, or because of your own personal experience.
