The 15th Annual Great Bay Half Marathon & 5k is returning on Sunday, March 26, 2023 for another delightful day of scenic New England running along the Great Bay estuary and historic downtown streets of idyllic Newmarket, NH! Half marathoners begin their race by traversing winding roads complete with captivating views (keep your eyes peeled for bald eagles and great blue herons), culminating with a downhill finish complete with beautifully restored buildings, centuries-old mills, and all the rich history the heart of Newmarket has to offer. Even better, all runners are rewarded with stylish swag, two complimentary beers (21+), and plenty of delicious and healthy snacks!
