Each person is seeded according to their pace per mile (refer to the seed order chart below). Please listen to the announcements for your seed to be called and proceed to the crosswalk between the Boston Common and the Public Garden. All walkers must seed themselves after the 10-minute mile pace. The seedings will be marked with balloons and signs on Charles Street behind the starting line. It is important to stay in your seed at the start to ensure smooth running throughout the race.
A slower runner or walker at the front of the pack could lead to injuries, should she not be able to keep up with the flow of the seed. With the ChronoTrack timing system, your start time does not begin until you cross the mats at the start line, so don’t worry about the time it takes to cross the line after the gun sounds. Do not try to run on either side of the mats, as your tag will not begin timing if you miss the mats.

If you need help during the race, move to the side of the road and contact the nearest Course Marshall or police officer. They will alert the Boston EMS medical bike team or ambulance that medical assistance is needed. If you see another runner in distress, please notify the nearest Course Marshall or police officer with the injured runner’s location.
Fill out the back side of your bib with any medicinal allergies you might have, as well as a local emergency contact.
Please be courteous to your fellow runners. Due to the size of the field, consideration of your fellow runners is essential to ensure a safe race. If you want to stop running, please pull off to the side before you stop.

Please note: Because the race is a USA Track & Field-sanctioned event, the rule states that baby strollers are not permitted. Runners pushing baby strollers are considered not “official.” If you choose to run with a stroller, please seed yourself in the stroller corral at the corner of Beacon and Charles Streets. Please run with your stroller on the left-hand side of the pack throughout the race – do not crisscross through the pack. Please do not bump runners’ feet with the stroller wheels, and remember to call out to surrounding runners when you are passing. Following these guidelines will prevent accidents and avoid harm to your child or to other runners.
There will be five water stations along the route and two on the Boston Common. Stay hydrated! Each mile will be clearly marked.
The results will be posted immediately after the race, near the awards stage. A complete results listing can be found on the website. The Post-Race Celebration & Awards will be held at 10:00 AM on race day on the Boston Common Parade Grounds.
