Half Marathon: Top 3 male & female overall, and age group awards: 18&U, 19-29, 30-39, 40-49, 50-59, 60+. Overall awards are based on gun time. AG awards are based on chip (net) time. Trophies/medals can be picked up at our office but any other prizes may only be claimed at the awards ceremony. Due to permitting and volunteer constraints, the half marathon will have time limit of 4 hours. 

Half Marathon Relay: Fastest female team, fastest male team, and fastest mixed team (at least one female and one male.) We’ve competed in enough relay races to recognize how difficult it can be to recruit enough people, let alone make sure they all show up on race day. For that reason, we’re doing things differently at the Charles River Half Marathon Relay. Teams can consist of two, three, four, or five runners per team, male or female. Each runner may run one, two, three, or four laps of the course, for a total of five laps per team. Any runner completing more than one lap must do so consecutively. So runner #1 on a 4-runner team cannot complete lap #1, then rest up and also complete lap #5. Team size and lap assignments must be finalized before the start of the race. 

BODYARMOR stations: There will be three BODYARMOR stations on the 2.6 mile loop: two along Greenough Boulevard, and one at the start/finish line. Each BODYARMOR station will have Sports Drink and Water.

Dogs and strollers: Sorry, while dogs and strollers are typically welcome in our events, we can’t allow either in this event.

We need volunteers!
We are seeking volunteers to help with several aspects of the event. Please sign up to volunteer at

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.

Postponement, Cancellation and Refund Policy:
All events are held rain or shine. In the event of severely inclement weather, an event may be postponed to another date. No refunds will be issued due to conflicts with the postponement date. If RACE must cancel the event due to circumstances beyond our control, no refunds will be issued. Please remember that all proceeds go to charity.
