I remember she got popped for PEDs or anti depressants or something back in 2020 and that's the last I've heard.
Her doctor gave her a prescription for a medical condition that she has. When she went to the pharmacy to fulfill the prescription, they gave her medicine from a pharmaceutical company that the pharmacy didn't realize had illegal added a substance that was on the track and field banned list. She was cleared of any wrong doing.
Brenda will be 35 this fall. She is finished as an elite runner.
I heard that the original plan was for her to make this her last year of competitive running, in order to make one last run at a global championships team, since it's the first time it's been held in the United States.
However, based on how she ran last year which was mediocre, even if she trains as hard as she can she has zero shot at making either the 800 or 1500 team.
It seems that the main reason she is still technically still a "professional" runner is in order to continue collecting checks from her sponsors. She had a solid career, but she is past her prime.
