QUALIFY FOR THE BOSTON MARATHON

Athletes must meet time standards which correspond to age and gender
  • For the 2021 Boston Marathon, qualifying times must be run on or after Saturday, September 14, 2019.
  • The qualifying times below are based upon each athlete's age on the date of the 2021 Boston Marathon (April 19, 2021).
  • Qualifying times are based on official submitted net time (also known as chip time).
  • Due to field size limitations, achieving one's qualifying standard does not guarantee entry into the event, but simply the opportunity to submit for registration.
    • In recent years, not all qualifiers who submit an entry have been accepted due to field size restrictions.
    • If the total amount of submissions surpasses the allotted field size for qualified athletes, then those who are the fastest among the pool of applicants in their age and gender group will be accepted.
  • See the current qualifying standards below.

Qualifying History 

Historically, runners who beat their qualifying standard by a larger amount of time are more likely to be accepted into the Boston Marathon. Due to field size limitations, as well as a heightened interest in participation, a varying "cut-off" time (a time below the minimum qualifying standard for age and gender) has been established. Below is a list of when entrants needed to obtain a faster time than their minimum standard in order to be accepted into the race:

YEAR FIELD SIZE "CUT-OFF TIME"* QUALIFIERS NOT ACCEPTED
2012 27,000 1:14 3,228
2014 36,000 1:38 2,976
2015 30,000 1:02 1,947
2016 30,000 2:28 4,562
2017 30,000 2:09 2,957
2018 30,000 3:23 5,062
2019 30,000 4:52 7,248
2020 31,500 1:39 3,161
