Additionally, anyone who develops any symptoms must avoid public activity except for going to get a COVID-19 test.

All participants must have a plan for isolation in the event of a positive COVID-19 test. Unvaccinated people must also have a plan to self-quarantine following an exposure to a COVID-19 positive person.


Masks will be required on Boston Marathon official buses and in all medical tents. Masks will be available across various locations associated with the Boston Marathon and Patriots' Day weekend activities.
