There’s more to running than just “left, right, left, right.” This slow-moving, endurance-building program focuses on proper running form, with an emphasis on lower back and core strength to help build strength and reduce the risk of injury. Each class combines dynamic and plyometric pre-workout stretches, a guided workout, and static post-workout stretching, with additional core and strength exercises assigned as homework. You’ll also learn how to track mileage using a device or an old-fashioned notebook to support your personal fitness goals. Most classes meet at Spy Pond.
