2026 Run to the Rock 5K, 10K & 1/2 Marathon

Race Information

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. The 10K and 1/2 Marathon run the same 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.
