Clark started practicing Brazilian Jiu-Jitsu at the age of ten at his father's academy in San Francisco, California, training with the adults as there were no kids classes at that time. At the age of 15 he accompanied his father to Rio de Janeiro, Brazil, where he remained for the next few years. He then moved back to the US to complete high school. He received his black belt in 2010 from his father, Grand Master Carley Gracie, at Rodrigo Medeiro's academy in Pacific Beach, San Diego. Clark Gracie is an active Brazilian Jiu-Jitsu competitor, and travels the world teaching while running Clark Gracie Jiu-Jitsu based in San Diego and La Jolla.
