From the organizer
Our 5K is held on one of the most beautiful courses in New England. It starts and finishes 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. We have the largest free raffle in New England, great food and a high quality race hat to the first 700 registered. We also offer 3 kids fun runs and a new playground to entertain the whole family
All proceeds of the GI5K go to Charity.
We hope you can join us for the 32nd Great Island 5K!
