History of the Great Cow Harbor 10K Run
The idea for the Great Cow Harbor 10K Run began in 1977 from the inspiration of John Rakucewicz, a local resident and running enthusiast. With over 1,000 participants, the first race was a huge success and became an annual event. Now the Cow Harbor Race is a beloved local tradition that celebrates the natural beauty of the area while supporting a myriad of national and local charities.
