Chloie Jonsson underwent gender reassignment surgery eight years ago. Her driver's license, Social Security card and even birth certificate identify her as female.
That isn't enough for CrossFit, which is not letting her compete in its tournament. The company claims she has an advantage over other women because of her genetic makeup.
"It was somewhat devastating to find out that I couldn't compete because this is what I do," Jonsson said. "This is what I train for."
"Chloie does not have an advantage over other women," her attorney Waukeen McCoy said. "And so, it's just mind-boggling to me that they haven't figured this out."
If Jonsson were competing for the Olympics, she would qualify as a female athlete because of the changes she has undergone.
ABC7 News contacted CrossFit about the lawsuit and did not get a reply.
