This will be the 40th year that the Tamalpa track club - Marin's premier running club - hosts the Marin Memorial Day races. These races are the primary fundraiser for the community activities supported by Tamalpa, including participating in running programs for at-risk youth, pancreatic cancer fundraising, and supporting the San Quentin 1000 mile running club.
