Chris Mosier is a trailblazing athlete, coach, and the founder of TransAthlete.com. In 2020 he made history by becoming the first transgender athlete to compete in the Olympic Trials in the gender with which they identify. Prior to that, in 2015 he became the first openly trans man to make a Men’s US National Team. Following the national championship race, he was instrumental in getting the International Olympic Committee policy on transgender athletes changed, and in June 2016 he became the first trans athlete to compete in a world championship race under the new rules, where he was the second-fastest American man in his group. He has been called “the man who changed the Olympics” by the BBC and New York Magazine. Chris is a six-time member of Team USA, All-American, and 2x National Champion. Beyond his athletic accomplishments, Chris is considered the go-to source for policy information and has helped numerous professional and recreational leagues write their guidelines and rules for the participation of athletes who are transgender.
