Thousands will flock to Northport Village to enjoy the annual Cow Harbor Weekend activities this weekend, but one will be doing it for the last time.

Anchored by the Great Cow Harbor 10K run on Saturday morning, Cow Harbor Weekend also includes a Saturday night concert and a parade and fair in the village on Sunday.

This year will be unique in that it is the last year Ken Savin, longtime Cow Harbor Weekend events chairman, will be organizing the festivities. In a phone interview on Tuesday, Savin said the task of managing the growing, nationally ranked was too large to continue with little help.

“It’s an enormous amount of work,” Savin, a Northport attorney, said. “I can’t do it. The volunteers just aren’t there anymore.”

Savin’s been at the helm for 10 years.

Aside from this year being the last for Savin, not much is different about this year’s race compared to previous years, he said. It has grossed about 5,000 participants, which is typical of previous years, he said.

“It’s the same Northport community, family-oriented day,” he said.

The band Group Therapy will perform on Saturday, Savin said.

The race will go on even after Savin leaves, he said — noting that the race committee has gotten prep down to a science. It’s unclear, however, who will step up to take charge over the rest of the weekend’s events.

On Sunday, the day begins with a parade down Main Street at noon. The parade features local bands, floats, sports teams, high school marching bands, antique cars and more.

Savin said an estimated 10,000 to 20,000 spectators flood the village on Saturday to witness the race, and somewhere between 20,000 and 25,000 people attend the Sunday festivities.

Asked why he thinks the race has grown in popularity in its nearly 40 years, Savin said he thinks it’s because “it’s consistent.

“Number one it’s a 10K race, not a 5K,” he said. “The location, you can’t pick a better location as far as scenery and it’s got the challenge of the hills. There are just so many things.”
