The Course

The Half Marathon

Start Time: 11:00AM

The Great Bay Half 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!

The 5K

Start Time: 11:00AM

The 5k starts at 11:00 AM! You’ll run (or walk) the same course as the half marathon up to Mile 2, at which point you’ll veer right into town. You will finish with a nice downhill stretch through the heart of downtown!

Post Race

Head over to the American Legion (151 Main Street) after you’ve crossed the finish line and be treated to craft beer from our friends at Smuttynose (21+), delicious food, and an assortment of healthy snacks after the race! The best part? Everything is included with your registration!
