Against the Tide Hopkinton

MBCC Against the Tide Hopkinton
June 14, 2025

Against the Tide is a family-friendly, multi-sport, rain or shine 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. Refunds are not allowed for this event.

Online registration closes at 5:00 PM the evening of June 13th. Walk-in registration is welcome the morning of the event at the registration tent starting at 7:00 AM.

Please note that water temperatures are not measured daily and can vary significantly depending on recent weather conditions and location within the course. While we do not have temperature readings for the full swim course, regular testing within the designated swim area at the Upper Beach has shown water temperatures ranging between 60°F and 64°F over the past month. These temperatures are a reasonable expectation for Saturday, June 14th, barring any major weather changes.

Wetsuits are permitted.
