Event overview
The Run to the Rock is set for September 12, 2026 in Marshfield, Massachusetts. All races start and finish at Furnace Brook Middle School, 500 Furnace Street. Distances offered:
- 5K
- 10K
- 1/2 Marathon
Registration is online only. The half marathon has a 3 hour course time limit and a minimum age of 13. Overall top three male and female finishers will be recognized in each distance. Age-group awards are given for the 5K and 10K (first place in each age group) and for the half marathon (top three in each age group).
Course and logistics
The 5K is primarily flat on an out-and-back route around the school and nearby neighborhood. The 10K goes toward the Pine Street area through a low-traffic neighborhood with a couple of hills. The half marathon travels into North Marshfield and reaches the North River along Union Street. Water stops are provided on each course - one around the halfway point for the 5K; at miles 2, 4 and 5 for the 10K; and multiple stops on the half marathon, with Gatorade at two of those stops. Restrooms are at the start/finish and at points on the half marathon course. Race shirts have a registration deadline of August 18. Race-day parking is at Furnace Brook Middle School, with overflow at the Boys & Girls Club of Marshfield. Dogs are not allowed on the course; strollers are allowed for the 5K and 10K and should start in the back. Visit the organization's website for the most recent information.
