About the Mass Half
The Mass Half runs through Worcester in the spring, timed to overlap with Boston Marathon training season, so many runners in the field are using it as a tune-up race. The course stays in the city, and the event is organized as a fundraiser for United Way of Central Massachusetts, which gives it a civic weight that goes beyond the running itself.
Thousands of runners are expected, which means a decent crowd along the route. The race is tied to local businesses and nonprofits across the region, so the post-race atmosphere reflects that broader involvement rather than just a standard finish-line setup.
