(Q) When will registration for the 2021 Boston Marathon open?
(A) Registration for the 2021 Boston Marathon will open towards the end of September 2020. The beginning of the qualifying window to be used for application and entry into the 2021 Boston Marathon has been established to be September 15, 2018, which means that we will accept qualifying performances posted for the 2020 event into the 2021 race, as well. Achieving and submitting a qualifying time during Boston Marathon registration does not guarantee acceptance into the Boston Marathon.
So do we think this means that someone who qualified for and was accepted to the 2020 Boston Marathon could potentially be rejected from the 2021 Boston Marathon? That seems a bit ridiculous.
Given there is an extended qualifying window for 2021 Boston, the only fair thing would be to increase the typical ~30,000 field size. They did it 2014 the year after the Boston Bombing, so there is a precedence. Either that or those 2020 accepted qualifiers should be granted automatic acceptance
