Course Information

Marshfield is the home of the famous Daniel Webster and his son Fletcher along with Edward, John and Josiah Winslow.  It's also had it's share of fame from Steve Carell (1/2 Marathoners will run by the Marshfield Hills General store, owned by him and his wife) and sports figures from the NHL, NFL, MLB and MLS as well as a Kennedy.​

The 5K course will take place primarily on the waterfront.  After looping through a local, quiet neighborhood you will find yourself crossing the Sea Street bridge, running along the beach and back over the Julian Street bridge to the finish line.

Both the 10K and 1/2 Marathon for nearly the first 5 miles as runners make their way from just outside of Marshfield Center along some of the backroads and tree lined streets that make up this area of town.  As you make your way towards the water the 10K will travel one street back from the South River as they head toward the finish line.  The 1/2 marathon will head into Marshfield Hills, skirt the edge of North Marshfield then return to Humarock and the finish line.

Volunteer Information

If you have an hour or two or more and would like to come help us out, please sign up here.  This is a great way for students, NHS, Scouts, confirmation classes as well as team building, promote your business or support the runners.  If you don't have a volunteer requirement to fill you can select a FREE future race (options will be provided).
