Our 5K is held on one of the most beautiful courses in New England.  Starting and finishing at the Great Island Common at the mouth of the Piscataqua River.  The course runs through the scenic and historic roads of New Castle NH. All proceeds of the GI5K go to Charity.

This year in celebration of our 30th anniversary, the first 600 registered will receive a pigment dyed crewneck sweatshirt designed by the DRIFT Collective.

We hope you can join us for the 30th Great Island 5K!
