Chris Mosier, the first transgender member of Team USA, appeared in a Nike commercial, which debuted during the Rio Olympics.
As Mossier bikes, runs and works out in various parts of New York City, the narrator asks, "Hey Chris, how did you know that you'd be fast enough to compete against men? Or strong enough?" Chris answers, "I didn't."
The ad closes with the brand's iconic slogan, "Just do It."
