Namibia Sprinters Banned From Events Due Elevated Testosterone

Namibian runners Christine Mboma and Beatrice Masilingi have been banned from all races from the 400-meter to 1600-meter range at the Tokyo Olympics due to "a natural high testosterone level," per the country's National Olympic Committee.

Mboma and Masilingi are two of the fastest 400-meter runners in the world. Mboma set the world's U-20 record for the 400-meter in June, while Masilingi ranked third in the world in 2021 behind Mboma and Olympic champion Shaunae Miller-Uibo of the Bahamas. But neither will be able to compete in the 400-meter for Namibia in Tokyo.

“According to the rules of World Athletics, this means that they are not eligible to participate in events from 400-meter to 1600-meter,” the Namibia National Olympic Committee said in a statement.
