We are thrilled to announce a powerful new chapter for an iconic Marin tradition. On Saturday, October 24, 2026 from 8 am - 1 pm, Zero Breast Cancer (ZBC) and Breast Cancer Prevention Partners (BCPP) will join forces for the annual Dipsea Hike for Prevention in Mill Valley, CA — a day of community, action, and hope on the legendary Dipsea Trail.
For the first time, ZBC and BCPP are coming together in partnership around a shared vision: a future with fewer breast cancer diagnoses and recurrences. Together, our organizations work to reduce breast cancer risk at both the individual and systemic levels — advancing healthier environments, empowering informed choices, and creating a future where prevention is accessible to all.
Meaningful change happens when we work together.
1 in 8 women will be diagnosed with breast cancer, yet 90% of cases are not linked to family history. By hiking and fundraising together, we’re supporting science-based solutions that help stop breast cancer before it starts.
Registration is $30. Your day includes:
- A scenic group hike through the redwoods
- Fundraising opportunities and sponsor prizes
- A post-hike celebration with light bites and interactive exhibits
- Practical ways to reduce harmful environmental exposures and lifestyle risk factors
- Bring your friends and family, start or join a team, and help create a healthier future for all.
