Great Cow Harbor Day Weekend

Great Cow Harbor Day Weekend




We look forward to seeing you this year for:
Cow Harbor 10k – Saturday, September 23, 2023
Cow Harbor Day – Sunday, September 24, 2023

Cow Harbor Weekend is a celebration of the Northport Community.

The weekend starts with Great Cow Harbor 10K race number pickup at the William Brosnan School on Laurel Avenue, Friday evening.

Cow Harbor 10K

The local Village population more than doubles Saturday morning with the running of the Great Cow Harbor 10-Kilometer Run that hosts 5,000 runners and twice as many spectators.

The Great Cow Harbor 10-Kilometer Run is one of the most prestigious foot races in the country and nationally ranked. Runner’s Worldhas named the Cow Harbor Race as one of the top 100 races in the USA.

The 2K Fun Run / Walk has been a huge success. This event attracts families and participants of all ages.

For more information, go to the Great Cow Harbor Race website.

No sooner does the race end Saturday morning and the festivities of the weekend commence.

Saturday afternoon is a transition period where the remnants of the race are removed and the set up for the Cow Harbor Day festival begins. Activities on the dock are plentiful as the Village is enjoyed by its many visitors.

The Cow Harbor festival is an event sponsor by the Incorporated Village of Northport. There are no corporate sponsors for Saturday evening or Sunday’s events. The weekend activities and events following the race are organized by a small committee of volunteers recruited by the Cow Harbor Committee Chairman, who is appointed by the Village Board.


Saturday evening hosts the annual Cow Harbor Weekend concert in the Village Park at 8:00 PM.

Simultaneously, on the Village Dock is the Lighted Boat display with trophies and prizes going to the best decorated boats. The boats and their crews decorate themselves in costume and accessories in accordance with an annual theme.

Sunday is a day whereby Main Street and the parking lots near the water are all closed and the cars give way to the 25,0000+ pedestrians that converge on Northport.

Cow Harbor Day usually has some unannounced, unpublished surprises for both children and adults. In the past, some of those surprises have included the United States Merchant Marine Academy Band, a US Coast Guard Cutter on the Dock, open for tours, Helicopters in the parking lots, US Coast Guard Rescue Helicopter demonstrations, and antique Warbird Flyovers.
