Suffolk County Marathon 2026

The Suffolk County Marathon is an annual Long Island race weekend featuring a full marathon, half marathon, 10K, 5K, 1K Kids Fun Run, and a Virtual Mile Mission. The main Sunday races begin in the Village of Babylon and conclude at Gardiner County Park in Bay Shore. Saturday races start and finish within Gardiner County Park. The 5K remains entirely within the park. Combo entries are available, including marathon-and-5K, half-and-5K, and 10K-and-5K, for participants seeking multiple events. The half marathon and marathon routes cross the Robert Moses Causeway, incorporating a distinct Long Island landmark rather than a simple road loop. The event accommodates a broad spectrum of runners and walkers; the 5K is open to ages 14 to 99, and a children's race is provided for younger participants. The Virtual Mile Mission allows participants to complete miles through various activities like walking, jogging, biking, swimming, or using a treadmill. This race series supports local veterans programs, with proceeds benefiting veterans on Long Island. The marathon has contributed over $1 million to local veterans' services.
