Event Overview

The 31st Annual Run to the Rock is a running event offering three race distances: a 5K, a 10K, and a Half Marathon. All races start and finish at Furnace Brook Middle School, located at 500 Furnace Street in Marshfield, Massachusetts.

Distances & Course

  • 5K: Described as a primarily flat course around the school and a quiet neighborhood, using an out-and-back route.
  • 10K: Travels towards the Pine Street area and through a low-traffic neighborhood with some hills.
  • Half Marathon: A longer course that goes into North Marshfield, reaching as far as the North River along Union Street.

Registration & Fees

Registration is online only, with different pricing tiers based on the date of registration (Early Bird, Standard, and "I waited until the last minute" registration). The half marathon has a course time limit of 3 hours, and participants must be at least 13 years old.

Event Details

A finisher's medal is given to all participants. Race shirts are available for those who register before a specified deadline. Number/bib pickup is available the day before the race at a separate location in Marshfield and on race morning at the school.

Hydration stops with water are provided on all courses, with some also offering Gatorade on the half marathon route. Restrooms are located at the start/finish area and at two points on the half marathon course. Parking is available at the school, with overflow parking at a nearby Boys & Girls Club.

Awards

Awards are presented to the top three overall male and female finishers in each distance. Age group awards are also given: first place for each age group in the 5K and 10K, and top three for each age group in the half marathon.
