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.

Fast & Flat
Park Run
High: 59°
/ Low: 42°
The half marathon has a 4 hour time limit.
The foliage, rural roads and scenery will take you on a 13.1 mile tour of what it is like to experience fall in New England. The USATF certified course starts with a 1 mile loop of the Look Park road to give your legs a chance to warm up. After that you will head out of the park and onto the bike path; this is your chance to take in the scenery and get ready for the slightly more inclined sections that lie ahead. The course takes a left on Mulberry Street and onto Audubon Road where you will find stone walls, peak foliage and barns along the road to distract you from the increasing incline. You will do most of the course’s climbing between miles 2 and 4 but this is paying it forward for a fast finish! You will make a sharp left onto Kennedy Street where you will take on the steepest climb of the day around mile 4. You can pick up your pace and give your legs a break as the course becomes a downhill roller coaster through quiet country roads until you make a left turn on Ryan Road around mile 7. You are now more than half way there as the course evolves into a flat and fast sprint through neighborhoods and historic Florence MA. At mile ten you will make a left turn onto Spring Street where you will find some climbing but don’t worry because the end is almost in sight! Spring Street becomes Main Street as you head into downtown Leeds before making a right turn back onto Mulberry Street. This is the time to pick up the pace because only a flat and straight section of bike path stands between you and the finish line in Look Park.
