One of the Most Prestigious 10K Races in the Country

Background

The Great Cow Harbor 10K Run will be held on Saturday, September 20th.  Runner's World has named the Great Cow Harbor 10K Run as one of the top 100 races in the US, and New England Runner regularly places it in its Top 100 Races, referring to it as a "winner" with a "big race atmosphere in a small town on the Island."  This race will sell out!

The 2K Fun Run/Walk has been a big success. This event provides something for everyone, from beginner runners to experienced athletes. Over 1,000 runners are expected to run in the 2K, while 5,000 people are expected to run the 10K.

A Race for Charity

The Great Cow Harbor 10K Run and 2K Fun Run/Walk is a nonprofit 501(c)3. We are proud to support the Special Olympics and other local organizations, like the Northwell Health Foundation,  the Ecumenical Lay Council Food Pantry, Save the Sound, the Northport American Legion Post 694 and the Lewis Oliver Farm Sanctuary.
