While he qualified, Mosier was uncertain about his eligibility to compete in the Duathlon Age Group World Championship Race in Spain in June 2016 due to the International Olympic Committee policy around the participation of transgender athletes, with specific provisions from the Stockholm Consensus in 2004. In 2015, Mosier challenged the policy, resulting in the creation and adoption of new IOC guidelines for the participation of transgender athletes. Mosier was considered the catalyst for change in the policy in January 2016, after he successfully advocated for change in the policy to allow his participation in the World Championship and future races. Following the policy change, in 2016 Mosier raced in the International Triathlon Union Sprint Duathlon World Championship race in Aviles, Spain, becoming the first known transgender athlete to compete in the World Championship race.
