Great Bay Half Marathon Sponsored by the Exeter Hospital
2017 will be our 11th year of the Great Bay Half Marathon and the Beyond The Rainbow 5K!
Sponsored by the Exeter Hospital, this annual race starts in a small New Hampshire mill town bordering on the Great Bay Estuary.
The course is challenging but beautiful as it winds its way along a designated scenic road. The race is large enough to close down the entire downtown for a spectacular finish with thousands of cheering fans. Come celebrate Spring with us in our home town of Newmarket, New Hampshire. With splendid views of the Great Bay and a closed course this is one celebration that will have you wanting to return, year after year.
