On June 6th 2015, out transgender athlete Chris Mosier finished 7th in the men's 35-39 category of the sprint duathalon at the Duathalon National Championship, earning him a spot on the national team which will represent the United States at the 2016 Duathalon World Championship in Spain, and making him the first openly transgender athlete to do so. In an interview with Outsports, Mosier said:
"Many transgender athletes stop competing when they transition categories. I want people to know it is possible to maintain an identity as an athlete and transition. When I was considering transition, I did not see transgender men competing at a high level in the way I aspired to compete. I am excited to be a visible example for other trans athletes or people considering a medical transition."
Mosier has long been a strong transgender advocate. In 2013 he founded transathlete.com, and is also a Co-Vice Chair of Trans* Inclusion at NASPA-Studnet Affairs Administrators in Higher Education. Additionally in the past Mosier has spoken to GLAAD about competing as a transgender athlete as well as transgender inclusivity in sports.
