    The 4th annual student led "Using Our Voices" Mental Health Run Series is an event grounded in the belief that students should be part of the change process, with genuine inclusivity achieved through active student engagement. It has now grown to include four districts: Patchogue-Medford, North Babylon, Connetquot, and New Hyde Park.

    The funds support students across Long Island by providing counseling opportunities and giving them the platform to display leadership, collaborate with peers from other districts, and contribute to an important cause.

    The event is designed and executed entirely by students, who are involved in every aspect, from planning to race day. The goal is to share crucial messages about reducing stress and anxiety, building relationships, and supporting mental and physical health through movement. This initiative also empowers students to work toward the NYS Seal of Civic Readiness by fostering civic engagement and community-mindedness.

    By supporting this series, you help students across the island unite for a cause that matters—promoting mental health and wellness. All proceeds benefit mental health organizations that work directly with our youth, amplifying the positive impact of this event.

    When kids are empowered, magical things happen!
