Riley Gaines slammed an Illinois woman who finished in third place behind two transgender competitors during a cycling race earlier this month after she came to their defenses amid criticism.

Tessa Johnson and Evelyn Williamson, who were both born male, beat out all the opposition at the Illinois State Cyclocross Championships. Johnson and Williamson both came under fire for taking spots from biological women as Kristin Chalmers was forced to third on the podium.

Chalmers told NBC News on Friday that "it would be ridiculous" to assert her life was "ruined" after finishing third and joined other cyclists in signing a letter in support of Johnson and Williamson.

Gaines, an OutKick contributor and host of OutKick’s "Gaines for Girls" podcast, said in a statement to Fox News Digital that Chalmers was a "traitor to women."

"Why is it so often women applauding their own erasure? Chalmers may claim she’s fine losing to men, but female athletes like her don’t have the right to willingly surrender the integrity of competition for everyone," Gaines said. 

"The majority of female athletes believe women deserve respect and fair competition. She is a traitor to ethical and fair sport. And she's a traitor to women."

In the letter, Chalmers and other cyclists called the controversy surrounding the event "manufactured."

"We refuse to be falsely presented as victims in a manufactured controversy driven to further alienate and marginalize those most vulnerable within our community, in service of rampant and harmful anti-LGBTQ+ legislation," the letter read, according to NBC. "We speak for ourselves: inclusion makes our sport and community stronger. Everyone is welcome here. Trans women are women."

Chicago CrossCup, which organized the cycle races, says on its website that it follows USA Cycling’s Transgender Athlete Participation policies for all of its races.
