Nike aired its first ever commercial featuring a transgender athlete during NBC's Olympic coverage Tuesday night.
The ad is titled "Unlimited Courage," and shows transgender athlete Chris Mosier running, cycling and working out while explaining the uncertainty he faced while tirelessly working toward his goals.
In the video, Mosier is asked, "How did you know you'd be fast enough to compete against men? Or strong enough? How'd you know the team would accept you? Or that you'd even be allowed to compete?"
His answer is always, "I didn't."
"Didn't you ever want to give up?"
"Yeah, but I didn't."
The video is part of a broader campaign in which Nike is highlighting athletes who are pushing boundaries,
.
35-year-old Mosier has competed in duathlons and triathlons since 2009, and while he's not competing in the 2016 Olympics, he has become the first openly transgender athlete to compete as part of a U.S. National Team.
"Every success that I've had since then has shown me that anything is really possible," Mosier told NBC News. "By not stopping myself, not limiting myself and just really going for it, I've learned a lot about myself and also had the opportunity to further the conversation on trans inclusion in sports."
