Transgender athletes are still able to run in the female category of UK women’s races almost six months after a ban was introduced to prevent them from doing so. The strict clampdown by UK Athletics was introduced in March but a glaring loophole in the rules, which were brought into effect to deny those who have been through male puberty from taking part in women’s athletics, has now emerged. As a result, the effectiveness and enforcement of the restrictions are under question. The rules imposed a ban on transwomen competing in the female category of any event under the jurisdiction of UKA. However, they also included a controversial exemption for competitions in which the places had already been secured.
