Transgender athlete Rachel McKinnon, a biological male who identifies as female, won the women’s Masters Track Cycling World Championships sprint title for the second year in a row.

“The 37-year-old, competing in the female 35-39 sprint category, had set a new world best time in qualifying,” according to the BBC. “The Canadian beat American Dawn Orwick for the gold, with Denmark’s Kirsten Herup Sovang claiming the bronze.”

McKinnon also took silver in the 500m time trial earlier in the week, BBC notes.

The athlete celebrated the win on social media and made a point of citing critics who’ve spoken out against biological men participating in women’s sports.

“This jersey, these medals, and this world record mean a whole lot more to me than my first,” McKinnon wrote via Instagram on Monday. “There were many more barriers this year, a much bigger spotlight, truly incessant hate and people doing everything in their power to have me banned, make me fail, and make me quit. But I didn’t. And I won’t.”
