Beatrice Masilingi has run 400 meters in 49.53.

However, a test, requested by the International Athletics Federation World Athletics, showed too high levels of the male sex hormone testosterone in her body.

Now she has spoken.

- My team is working on that right now, she says according to Sportbladet.

- I still hope to run 400 meters, we will see what happens, she says.

"Can't stop"

Masilingi believes that the message will not stop her.

- I can not quit just because of a rule.

- The support has been fantastic from all over the world, it was really not something I had expected so I am really grateful.

The 18-year-old was at Stockholm Stadium on Sunday and competed in the Diamond League.

She ran 200 meters and finished third in 22.65.
