The Jersey Shore Half Marathon is a fast course at the Sandy Hook Unit of Gateway National Recreation Area. It's a flat as a pancake course, so it's great for shooting for a PR. I speak from experience as I set my half marathon PR on the course. It's basically a lollipop course that has two short loops at the end of a longer out and back. A portion of the out and back is run twice to hit the 13.1 mile distance. It's a pretty course that takes you around the lighthouse entirely on road. Water stations are frequent and were staffed by enthusiastic volunteers. Parking is easy and plentiful while being very close to the start/finish area.
