Organizers of next years Boston Marathon announced Monday that nonbinary athletes will be allowed to run the prestigious race without having to register as members of the mens or womens divisions.

The Boston Athletic Association said that it is currently working on expanding opportunities for nonbinary athletes, not just at the marathon but also at the other races the association administers.

Registration opened Monday for the 127th Boston Marathon, scheduled for April 17 next year. The BAA is expecting a field of about 30,000 for the race, one of the most competitive in the world.

According to the organization, nonbinary athletes who have completed a marathon as a nonbinary participant during the current qualifying window can apply for the 2023 Boston Marathon. Entry into the event will be determined by the athletes submitted time and the marathons overall field size limit. The registration application will include a nonbinary gender option for runners to select.

While we do not currently have qualifying standards for non-binary athletes, we are working on ways non-binary participants are accepted into the event, the BAA said. Discussions are ongoing with non-binary athletes in an effort to further promote inclusion at all BAA events.
