Happy Valley Half Marathon & 5K Florence, MA   Oct 19, 2025

The Happy Valley Half Marathon was created to bring you a breath-taking course, designed to showcase some of the most beautiful roads that New England has to offer, during peak Fall foliage. The Happy Valley experience only gets started at the finish line. Your achievement will be celebrated with breweries, food trucks and the enthusiastic support of the local running community. Speaking of community; this is an event that makes a positive impact year round as the Happy Valley Half Marathon & 5K has partnered with the Campaign for the Cooley Dickinson’s new Emergency Department to help make our community safer, happier and healthier.

The Happy Valley Half Marathon & 5K takes place during the peak of the fall season in beautiful Western MA. There is so much to do that we think you should come for the race and stay for the weekend!
