The Boston Marathon will welcome nonbinary athletes in 2023.

To enter, nonbinary runners must have completed a marathon as a nonbinary participant during the qualifying window, which ends on Sept. 16, 2022.

The current times for entry mirror those in the women's field.

"With this being our first year, we do not yet have enough data to establish non-binary qualifying times," the Boston Athletic Association says on its entry form.

The Boston Athletic Association says those times could be updated as it gets more data.

Organizers say they are also working with nonbinary athletes to promote inclusion at all events put on by the Boston Athletic Association.
