While there's still a lot to do to help nonbinary runners and the entire nonbinary community as a whole, this is an important step to grant social acknowledgment to nonbinary athletes as well as to promote inclusion in sports. This was the correct decision as proven by the high participation in the 2022 Brooklyn Marathon and Half Marathon.
The Boston Athletic Association is the latest race organizer to cave to pressure from the "woke" left, following the examples of the Philadelphia Distance Run and the Brooklyn Marathon. This new category is unnecessary as nonbinary long-distance runners comprise a tiny minority of race participants. The creation of different categories is almost reaching absurdity.
