Great Cow Harbor 10K Run

Great Cow Harbor 10K Run is a nationally recognized 10K road race in Northport, New York, USA, combining elite-caliber reputation with the charm and energy of a harbor-town community event. Organized by Great Cow Harbor-10 Kilometer Run, Inc., a nonprofit 501(c)(3), the race has become one of Long Island’s signature running events, drawing thousands of participants to the Village of Northport each fall. What makes it distinctive is the contrast between setting and stature: although the event takes place in a relatively small town, it consistently attracts a large field, strong competition, and the kind of local crowd support usually associated with much bigger-city races. The official race materials emphasize its standing as one of the country’s most prestigious 10Ks, while the event’s charitable mission helps tie it closely to the surrounding community.
