Great Bay Half Marathon, 10K, & 5K

Conquer New Hampshire’s Best Spring Road Race

The Great Bay Half Marathon, 10K, & 5K returns in April 2025 for a run that’ll have you hitting your “peak!” Conquer the Great Bay hills with a challenging race on the half marathon course or take the slightly flatter route on the 10k or 5k! Either way, you will experience spectacular views of the Great Bay Estuary and historic Newmarket, NH.

But don’t let the captivating views fool you! This demanding course is “mound” to take your breath away. To celebrate one hill of a run, you’ll be rewarded with stylish swag, complimentary beer (21+), and plenty of delicious and healthy snacks at the post-race party!
