Megan Youngren, a biological male who transitioned to become a transgender female, will become the first openly transgender athlete to qualify for the U.S. Olympic marathon trials later this month, according to Sports Illustrated.
Youngren, who came out as transgender in 2012 and finalized her official paperwork for the transition in 2019, meets the International Olympic Committee standard of testosterone levels allowable for biological men to compete as transgender women.
Youngren began seriously running in 2013, and pushes back against the claim that qualifying for the women's trials is easier due to being born male.
The issue of whether biological males who become transgender women should be able to compete against biological women in sports is far from settled.
In Connecticut, some high school girls' runners have filed a federal lawsuit to prevent transgender girls from being able to compete, citing the inherent unfairness of such an arrangement.
