The much-discussed Caster Semenya will not play at the Olympic Games in Tokyo.
The thirty-year-old athlete failed to qualify for the 5,000 meters on Friday.
She ran 15.32.15 minutes in a specially arranged limit match in Durban, South Africa, but that was well above the required 15.10.00 minutes.
Semenya is the two-time Olympic champion in the 800 meters, but is not allowed to defend her title in Tokyo at this distance.
She belongs to a small group of athletes with a naturally high testosterone level.
According to the World Athletics Federation, these athletes have a disproportionate advantage over distances of 400 meters to an English mile (1,609 meters) due to the muscle-strengthening effect of the hormone.
Only by taking inhibitors would Semenya be allowed to reach her favorite distance, but she refuses on principle.
The South African is still fighting a legal battle to get what she thinks is inhumane rule undone.
Semenya has so far lost all the lawsuits she filed and has now pinned her hopes on the European Court of Human Rights.
Semenya previously announced that she would be aiming for the 200 meters for the Tokyo Games.
But the athlete, who is also a three-time world champion in the 800 meters, did not do so.
"I am 30 years old and sprinting is not good for my muscles. Long distances are better for me," she said in April after her first failed attempt to run the 5,000 meter limit.
