Join us for the 28th Annual Marin Human Race! The Marin Human Race is a fundraising event for the benefit of any participating nonprofit agency or school in the Bay Area. Attended by over 4,000 people, this race is the largest collaborative fundraiser in the county. Thanks to generous sponsors, the Center is able to return 90% of all donations raised to the community*. Last year the Center returned over $350,000 to the community for the benefit of 115 nonprofits and schools.
