Track and field banned transgender athletes from international competition Thursday.
The World Athletics Council adopted the same rules as swimming did last year in deciding to bar athletes who have transitioned from male to female and have gone through male puberty. No such athletes currently compete at the highest elite levels of track.
Another set of updates, for athletes with differences in sex development, could impact up to 13 current high-level runners, World Athletics Council President Sebastian Coe said.
“All the decisions we've taken have their challenges,” Coe said. “If that's the case, then we will do what we have done in the past, which is vigorously defend our position. And the overarching principle for me is we will always do what we think is in the best interest of our sport.”
