Lace up your running shoes for the 31st Annual Run to the Rock, returning to Marshfield, MA, on September 12, 2026. This popular event offers a distance for every runner, with a Half Marathon (13.1M), 10K, and 5K, all starting and finishing at Furnace Brook Middle School. As you race, you'll be supporting a great cause, with proceeds benefiting The Boys & Girls Club of Plymouth and Marshfield.

Experience the diverse beauty of Marshfield on these entirely paved road courses. The 5K presents a largely flat and fast route, guiding runners through a quiet neighborhood and towards the picturesque waterfront, including a stretch along the beach. For those tackling the 10K, the journey heads towards the Pine Street area, offering a scenic tour through beautiful, low-traffic neighborhoods with a couple of rolling hills to challenge you. Half Marathoners embark on an expansive adventure into North Marshfield, exploring areas as far as the North River along Union Street and skirting Marshfield Hills before returning to Humarock. Expect some hills on the longer distances, adding to the rewarding challenge.

Runners can anticipate well-supported courses, with hydration stops strategically placed approximately every two miles across all distances. The Half Marathon also features Gatorade at miles 6.8 and 9.8, while water and snacks await all participants at the finish line. Typical race day conditions in mid-September bring comfortable highs around 75°F and lows around 55°F, with only a 13% chance of precipitation. With ample on-site parking at Furnace Brook Middle School and overflow at The Boys & Girls Club of Marshfield, the Run to the Rock promises a memorable race experience for all.
