Sackets Harbor Marathon & Half Marathon Sunday, September 5, 2027

The course

Out-and-back. Lakeside. Certified.

Both races start and finish at the Madison Barracks Polo Field on Pike Rd, on Lake Ontario's Black River Bay. The course heads out through the village, down Main St, and onto quiet, rolling country roads. The half turns at mile 6.55; the full continues to 13.1. On the way home the route eases downhill, goes along the water, then runs flat through the village on Washington and Broad to the finish at the Polo Field. Rolling early, gentle late.

The one rule

⬅️ Run LEFT.

It's an out-and-back, so there's two-way runner traffic most of the morning. Stay to your left, especially near the turnarounds. We've worked with local authorities to minimize traffic, but a few local vehicles may appear, so stay alert.

Half turnaround (mile 6.55): stay left, loop around the sign, head home.

Marathoners: stay left and keep going; your turn is at 13.1. Turning at the half turnaround as a full registrant is a DQ, not a half finish. Rules of competition

The turnaround signage runners need to recognize

Support

Aid every ~1.5 miles, a toilet at every single one

Water and lemon-lime Gatorade at every station. Bring your own gels; drop trash at stations or mile markers. Every station is run by a local team competing for your post-race vote: the Water Station Contest.

🍌 Bananas at mile 6 for everyone, again at mile 7 on the way back for the half, and at miles 8, 13.1, 18.5 and 20 for marathoners.

🍊 Orange slices at the half marathon turnaround: everybody passes it at mile 6.5, and marathoners get a second pass at 19.5 on the way home.

It counts

Both courses are USATF certified.

Both were measured by Don Hughes, who has certified over 100 courses in 18 years. Certification is what makes a time count. The marathon's certificate is what makes it a Boston qualifier. The half's counts for records and rankings; Boston only takes marathon times.
