The Spin-A-Thon is a fun endurance challenge and a great team-building activity which offers several ways to participate. Take part in the action by organizing or joining a spin-bike team or become an event sponsor. Proceeds raised benefit Kids in Distress, a leading force in the prevention of child abuse and neglect and Children’s Diagnostic and Treatment Center, which promotes health and well-being of children and youth with special healthcare needs. Registration begins at noon and the Spin-A-Thon is from 1 to 7 p.m. Sponsored by Marine Industries Cares Foundation and Riverwalk Trust. • Esplanade Park 400 S.W. Second St.
