The world's best female pedestrians also want to compete at 50 kilometers at the Japan Olympics this summer. But their case is not filed in the sports arbitration court Cas.
Cas writes in a statement that they do not have the legal right to make a decision on such a case.
The seven active, including the 2017 world champion at distance, Ines Henriques, had reported both the International Olympic Committee and the International Athletic Association to Cas.
In the World Cup, the female walkers have competed for 20 and 50 kilometers since 2017, but still have only the shorter distance on the Olympic program.
