The Experience

The Half Marathon-by-the-Sea, first run in 2014 and now in its 12th edition, draws runners from about 26 states to Manchester-by-the-Sea, MA. With a median field size of around 855 finishers, this race has seen steady growth.

This certified course is known for its fast, flat profile, making it a prime location for personal bests. Runners will experience a scenic journey through the historic downtown of Manchester-by-the-Sea and past the tranquil freshwater lakes of nearby Hamilton. While the course is largely paved road, be aware of brief sections on gravel or dirt that require attention.

Despite some reviews noting open roads with minimal traffic, the overall production is considered well-organized. Runners can expect a tech shirt as part of the swag, and the race aims to provide a rewarding experience for those seeking a swift and scenic half marathon.
