Race Overview

EST. 2007

The Hamptons Marathon is a small, quiet race on the eastern end of Long Island, and that smallness is the whole point. The field is compact, the roads are flat, and by late September the summer traffic is mostly gone. You start and run loops through the roads around East Hampton, and the course stays low and close to sea level the whole way. With equal gain and loss spread thin, there's nothing here designed to break you on the hills. But multi-loop courses have a way of testing you mentally in the back half. Don't go out too fast just because the first loop feels easy.

This is a decent shot at a PR if you're suited to flat, calm racing and can keep your head together through the repetition. The field is small, which means less crowd energy and no one to chase if you go out too hard, so run your own race from the start. Weather in late September can be close to ideal, with cool mornings that warm up to something manageable by the finish. Open registration means getting in is straightforward, just don't wait too long once you've committed. If you're staying out east, book early as lodging near East Hampton fills up.

The course is a multi-loop on the roads around East Hampton, with essentially no net elevation change. Total gain and loss are equal and modest, spread across terrain that stays almost entirely flat, with the highest point under 40 feet above sea level. That flatness is the defining feature: there are no significant climbs to manage and no long descents to bank or fear. Pacing should be even from the gun. The main variables to watch are wind, which can shift on exposed coastal stretches, and late-race fatigue amplified by the repetitive nature of multi-loop courses. Focus on negative splitting rather than going out hard.

What to expect

Late September in the Hamptons tends to be one of the better windows for racing on Long Island. Mornings start cool enough that you'll want a throwaway layer at the start, but by the time you're deep into the race it's usually comfortable, not hot. Humidity is lower than summer, and you won't typically be managing heat as a serious factor. That said, wind off the water can be unpredictable on exposed stretches, so pay attention to the forecast in the days before and be ready to adjust your pace targets if it's breezy.
