Billie Jean King is among more than 60 athletes urging international track and field’s governing body to rescind its new standard on natural hormone levels for female runners.
The tennis champion joined the athletes in an open letter asking the IAAF to end its policy passed in April that limits testosterone levels for middle-distance runners. Two sports groups — the Women’s Sports Foundation and Athlete Ally — released the letter Tuesday.
Soccer’s Megan Rapinoe, hockey’s Meghan Duggan and softball’s Jessica Mendoza are among the signees. They say the standard discriminates against female athletes and “no woman should be required to change her body” to compete in sports.
