Join us for a Boston-qualifying Marathon and Half Marathon through the scenic lake-side village of Sackets Harbor and the surrounding area. This is an out-and-back course with the START and FINISH of both races on Pike Road along the Madison Barracks Polo Field in Sackets Harbor, NY. You will enjoy several miles along Lake Ontario before heading out to some beautiful country roads. Because the views along the lake are so awesome, you will run lake-side again, through the village, with a magnificent finish back at the Polo Field.
