The new IAAF regulations limiting testosterone levels in female athletes, will kick in next Wednesday.
This is after Caster Semenya and Athletics South Africa lost their challenge in the Court of Arbitration for Sport. The final races before new rules about who can compete in certain track events on the international stage take place on Friday.
That means the first Diamond League meeting of the season, in Doha on Friday, will not be affected by the new IAAF regulations, with a women’s 800m race taking place on the day.
Caster Semenya has not entered, however, two of the women who have competed with Semenya recently, Kenya’s Margaret Wambui and Francine Niyonsaba from Burundi, are in the entry list.
British athlete, Lynsey Sharp, who has been vocal in her belief that racing against Semenya is unfair, is also on the list. The Court of Arbitration for Sport this week ruled against Semenya, although it admitted that the regulations limiting levels of naturally produced testosterone in women is by definition, discriminatory.
Moments after the verdict was announced on Wednesday, Semenya took to Twitter, posting an emoticon of a man shrugging, along with the words: “Sometimes it’s better to react with no reaction”.
