Dear Great Bay Participants,

We regret to inform you that the Great Bay Half Marathon & 5K will not return in 2025 and beyond.

We want to express our gratitude to the Newmarket running community, including local officials, who have been vital in helping us execute this race year after year.

We appreciate your support over the years and invite you to explore other Nor’Easter Run Series and Ventures Endurance events.
