The Experience
The Suffolk County Half Marathon starts in the Village of Babylon and finishes at Gardiner County Park in Bay Shore, treating runners to one of Long Island's most scenic race courses. The highlight is the Robert Moses Causeway, where the Great South Bay stretches out on either side — a rare chance to run across a major bridge with water views all around.
Now in its 12th year, the race has grown to about 1,600 finishers and draws runners from roughly 15 states. The point-to-point route is mostly flat and fast, making it a popular choice for those chasing a Boston qualifier or a personal best. With a winning time around 78 minutes, the field is competitive but welcoming.
After the race, the finish at Gardiner County Park offers a relaxed setting to celebrate. Whether you're aiming for a PR or simply soaking in the bay views, this half marathon delivers a memorable Long Island experience.
