From the Organizer


Course: The 3.11 miles race will be held on the scenic, flat, and winding paths along the Charles River at Boston's Herter Park.


BODYARMOR Hydration Stations: There will be two BODYARMOR stations, one at mile one and another at mile two. Each BODYARMOR station will have sports drink and water.

Dogs and strollers: You are welcome to run/walk with your dog or stroller, but please start at the back and pass cautiously and respectfully. The event is held on narrow park paths so there's not much room for passing.

We need volunteers!
We are seeking volunteers to help with several aspects of the event. 

Public Transportation: Harvard Square MBTA Station is a 1.1 miles away. The 70, 70a, and 86 buses will drop you .1 mile away at Western Ave & Everett St. Plan your trip here: Google Trip Planner

Parking: There’s a large parking area (lot #4) at 1101 Soldiers Field Road next to the start/finish area.
