Kayla Harrison began training in judo at age 6 and is the first American ever to win an Olympic gold medal in the sport, which she did in both 2012 and 2016. Yet her competitive success masked an unimaginable personal struggle. At the age of 16, she revealed that she had been sexually abused by her coach for years. Today, Kayla uses her gold medal profile, voice, and example, as well as her Fearless Foundation, to encourage and empower other survivors of child sexual abuse. Now retired from competing in judo, Kayla is moving into mixed martial arts with the Professional Fighters League. She lives and trains in Boston. Cynthia S.
