The field size was reduced by 36% this year while another 28,000 runners participated in the race virtually.
Runners were required to provide proof of vaccination or a negative COVID-19 test. Although masks were not mandated for the 26.2-mile course, face coverings were enforced on participant transportation, as well as for volunteers who interacted with participants.
According to the Boston Marathon Association, 95% of all Boston Marathon volunteers were vaccinated and 100% of Boston Marathon medical volunteers were vaccinated.
