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.
