Chris Mosier is a trailblazing athlete, coach, and 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 and was instrumental in getting the International Olympic Committee policy on transgender athletes changed; in June 2016 he became the first trans athlete to compete in a world championship race under the new rules. He has been called “the man who changed the Olympics” by the BBC and New York Magazine. Chris is an eight-time member of Team USA, representing the United States in the sprint triathlon and the short course and long course duathlon, a five-time Men’s National Champion, and a Men’s All-American.

Chris’s website transathlete.com is the go-to source for information about transgender athletes in sport. Chris has written and advocated for policy change from the high school level to national governing bodies and professional leagues. He has become one of the leading grassroots organizers against the current wave of anti-trans legislation across the United States, and when not fighting the good fight, he mentors transgender and non-binary athletes around the world in hopes that he can live by his motto of “be who you needed when you were younger.”
