From there, the race heads south along Great Neck Road, with a couple of detours along Great Pines Road and Tracy Lane and Red Brook Road, before bringing runners all the way south to the parking lot at South Cape Beach. Once there, they’ll make the turn and run back all the way north along Great Neck Road, back to the finish line where they started. After runners finish the race, which is presented by the Naukabout Beer Company, they’ll get to enjoy a post-race party with live music and Naukabout Beer for all finishers over 21, as well as a custom finisher’s medal and sunglasses.
