Race Info
The Suffolk County Half Marathon starts by the Babylon train station in Babylon Village and runs east along Montauk Highway before crossing the Robert Moses Causeway bridge over the Great South Bay toward Captree. It turns back over the same bridge and finishes at Gardiner County Park in Bay Shore. The course is USATF-certified and flat apart from the causeway crossing, which is the one real climb. It runs on the Sunday of race weekend, alongside the marathon and 10K.
