Great Bay Half Marathon

Newmarket Mills
55 Main St.
Newmarket, NH 03857
United States

The 13th Annual Great Bay Half Marathon & 5k is returning to Newmarket, NH on Sunday, April 7, 2019 for another day of scenic New England running by the Great Bay estuary! Join thousands of runners and spectators at New Hampshire’s best spring road race, where you celebrate your finish with an after-party featuring Smuttynose craft beer and plenty of food!

The Great Bay Half Marathon

The Great Bay Half Marathon boasts a challenging but gorgeous course along the Great Bay estuary, featuring a 3.5 mile section on a well-maintained winding dirt road, sightings of bald eagles and great blue herons, and a dramatic finish in the heart of historic Newmarket. Just picture yourself on the final downhill stretch of closed downtown streets running past the centuries-old fieldstone mill buildings and throngs of cheering spectators!

We also provide some on-course entertainment for your running pleasure! Weather permitting, there will be live music at four locations along the course to keep you motivated. Also keep on the lookout for the belly dancers from Lotus Rising Belly Dance at Mile 10!

The Center for Orthopedics & Movement 5K

The Center for Orthopedics & Movement 5k aims to bring awareness (and donations) to Exeter Hospital’s The Beyond The Rainbow Fund – helping local NH cancer patients since 2002. Learn more here.

The 5k starts at the same time and place as the half marathon! You’ll run (or walk) the same course as the half marathon up to Mile 2.5, at which point you’ll veer right when the marathoners stay straight. The course then goes up a short steep hill (sorry!) but finishes with a downhill stretch through the heart of downtown with thousands of cheering spectators!

The After Party

Not only do you get a wonderful day of amazingly scenic running, but you’re also treated to an after-party at Schanda Park on the banks of the Lamprey River featuring delicious local pizza, healthy Stonyfield Yogurt, energy Bars, and Hint flavored water (look for the big white tent). As if that weren’t awesome enough, runners 21+ get two tasty Smuttynose craft beers! Simply head on over to The Riverworks restaurant or the American Legion when you’re done eating. The best part? It’s all included with your registration!


Registration and packet pickup take place at Newmarket Mills, 55 Main Street, Newmarket, NH 03857. Please arrive by 9:30 a.m. to ensure you have time to park, check-in, and stretch before the race begins at 11 a.m.

Both the half and 5k start at 82 Main Street in front of Newmarket Mills and finish just two blocks down the street.

The after party takes place at Schanda Park for the food and at The Riverworks restaurant and the American Legion for beer.
