27th Annual Cape Cod Against the Tide

June 27, 2026 | Brewster, MA

Against the Tide is a family-friendly, multi-sport event to benefit Massachusetts Breast Cancer Coalition (MBCC). MBCC is the only non-profit in the state dedicated to the prevention of breast cancer from environmental causes. The funds raised through Against the Tide help to support and expand our community education program Let’s Talk Prevention: Reducing Toxic Exposures, MBCC Webinar Series, and the newly-expanded student environmental health program, Let’s Talk Prevention: Actions You Can Take. We are grateful to all of you who help prioritize breast cancer prevention. Above and beyond your commitment to participate in the Against the Tide event, we hope that you will also fundraise on behalf of MBCC and our important mission to change the legacy of breast cancer for future generations.
