At all BRR events, participants should conduct themselves in a courteous manner, respecting all fellow participants, volunteers, event staff, and members of the community, and following the Rules of Competition. Unsportsmanlike conduct will not be tolerated.

Proper race etiquette is required at all times, including being aware of your surroundings and of announcements and instructions from event officials.


Please give yourself enough time to pick up your bib number and enter your corral. Only enter the corral you are assigned to or a slower one, and respect the event staff. Please be respectfully quiet during pre-race announcements and the playing of the National Anthem prior to the start.


The use of headphones is strongly discouraged. If you must wear headphones, be sure that you can hear all announcements and be extra aware of your surroundings, including other participants.


The use of mobile devices for photography or social updates during the event is strongly discouraged, as it decreases your awareness of other participants around you.


In accordance with the State of Massachusetts Department of Conservation and Recreation rules and City of Boston rules, please use only the toilet facilities provided. Please be considerate in portable-toilet lines; don’t cut in line or into another line. Never urinate in the corrals, at the post-finish walk-off, or in park woods, or you will risk disqualification and a police summons.


While participating in the event, don’t run in groups of three or more abreast; wide groups become barriers to other runners. Don’t stop abruptly to drink at an aid station or to tie your shoelaces. Watch where you spit and blow your nose to avoid hitting other participants. If someone running behind you says, “On your left,” move to your right to let the runner pass. If someone says, “On your right,” move to your left.


BRR events are conducted in public places—either city parks or streets. Please deposit any trash in the provided receptacles, including at aid stations. Be careful when discarding cups at aid stations to avoid hitting other participants.


If another runner appears to be in distress, please offer assistance and/or notify volunteers.
