Organizers of the 127th Boston Marathon added a category for non-binary runners in next year's race in an effort to be more inclusive.
The Boston Athletic Association (BAA) announced on its registration website that it was "currently working on expanding opportunities for non-binary athletes at our events, including the upcoming 2023 Boston Marathon."
"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," BAA said.
"With this being our first year, we do not yet have enough data to establish non-binary qualifying times. Therefore, we will use the times listed here, as they are inclusive of the qualifying times for the two existing divisions. As we prepare for future races, participants can expect non-binary times to be updated accordingly," BAA said.
For non-binary runners to participate in the race, they must have completed a marathon as a non-binary participant during the current qualifying window of Sept. 1, 2021 through Sept. 16, 2022.
The window to register opened on Sept. 12 and will end on Sept. 16.
"We view this first year as an opportunity to learn and grow together," BAA said.
Transgender non-binary Olympic runner Nikki Hiltz welcomed the move.
"Thereís still so much work to be done, but Iím thrilled that non-binary runners are being acknowledged by the Boston Marathon and BAA," Hiltz said on Twitter.
A field of about 30,000 is expected for the race scheduled on April 17, 2023.
The Boston Marathon is the latest major marathon to begin adding a non-binary category.
Last year, the Philadelphia Distance Runner became the first elite road race in the United States to establish a non-binary division and offer equal prize money.
