Course breakdown

Marathon (42.2 km)

The start and finish are located at Southampton Intermediate School. The course provides a flat, fast run through Southampton Village with views of the Atlantic Ocean, Shinnecock Bay, and Coopers Beach.

From the starting line, runners head south down Old Town Road before heading northeast along tree-lined Wickapogue Road, Downs Path, and Flying Point Road. This loop and the return to Old Town Road make up the first four miles of the course with some minor ups and downs.

You begin your race through Southampton Estates, run down wooded roads, and enjoy gorgeous beaches on either side of Meadow Lane. The course is as flat as can be, though you'll find flat with no true hills but lots of slight inclines and declines.

The race gets very quiet for marathoners after splitting off from the half marathoners. The last 6 miles or so may have a small amount of traffic on the road because it's not completely shut down.

Half Marathon (21.1 km)

Marathon and half marathon runners start together and finish at the same finish line. The half follows a single loop through the same spectacular route. Most of the course isn't shaded, which puts you at the mercy of the sun, but that also leads to great views of beautiful houses, ponds, and beaches along the way.

5K

The 5K uses a portion of the main course, offering a taste of Southampton's scenery with an equally flat profile, ideal for beginners or those seeking a fast race.

What weather to expect

Late September in Southampton typically offers pleasant running conditions. Temperatures generally range between 10°C (50°F) in the morning and 17°C (63°F) during the day. There's about a 43% chance of rain, with an average of 3.5 mm of precipitation per day. Wind averages 21 km/h (13 mph).

These conditions are generally favorable for racing. Plan for light, adaptable clothing: a tank or technical t-shirt, possibly with a light long-sleeve layer at the start. Since most of the course isn't shaded, consider a cap and sunscreen if the sun's out. Hydration will be essential—take advantage of every aid station.

Race strategy and tips

Pacing management

With its fast and flat course, you can set your next personal best or join other racers on the quest to earn a Boston Qualifying time. Don't get carried away by the flat profile at the start. The slight undulations may seem insignificant, but they engage different muscle groups. Establish your rhythm from the first kilometer and hold it.

On the marathon, the fact that the course is a double loop lets you mentally map the route from the first half. Use this knowledge on the second lap—you'll know exactly where to push and where to conserve energy.

Nutrition and hydration

Water is provided at each aid station, and there's also usually sports drink at each station. Aid stations are spaced about every 1.5 to 2 miles (2.4 to 3.2 km).

Never test new nutrition on race day. Carry your own gels or bars if you have specific preferences. On the marathon, plan for carbohydrate intake every 45 minutes or so. On the half, two or three gels may suffice depending on your experience.

Managing the lack of shade

Most of the course isn't shaded. In sunny conditions, your body overheats faster. Pour water on your head and neck at aid stations. Start hydrating from the first station, even if you're not thirsty yet.

Mental management in the final miles

The race gets very quiet for marathoners after splitting from the half marathoners, with not much crowd support on the course, though volunteers at aid stations and local law enforcement are wonderful. Prepare yourself mentally for this solitude. This is where your psychological preparation makes the difference.

What makes this race special

Known for its intimate atmosphere, the race hosts 200-400 runners and is celebrated for its scenic beauty, exceptional organization, and vibrant post-race festivities. Many aid stations are manned by local families—kids of all ages handing out water and Gatorade, and everyone is super friendly and encouraging.

There is free parking within walking distance of the start/finish line available on a first come, first served basis. It's highly recommended to arrive by 6:30 AM to secure a spot. Bib pickup takes place on race day.

With the course USATF certified, you can use your time to qualify for other major races. Both the marathon and half marathon can serve as a great training run for those preparing for NYC, Marine Corps, or Chicago marathons.
