More than 600 people turned out for the Zero Breast Cancer’s 12th Annual Dipsea Hike on Saturday, Sept, 13 in Old Mill Park, raising nearly $70,000 in the process. 

The San Rafael-based nonprofit organization, which focuses on research, prevention and education, has been hosting the event since 2002, seeking to both heighten awareness of the benefits of physical activity in reducing breast cancer as well as raise mont for continued research. The event has raised more than $300,000 in support of ZBC’s research and educational programs and more than 3,100 people have participated.

The Dipsea Hike for Zero Breast Cancer is an all ages noncompetitive 6-mile course starting at the Dipsea steps in Mill Valley. This year’s honorary event chair, inspirational speaker and lead hiker was Astronaut Yvonne Cagle, who graduated from Novato High in 1977.
