Silvio Duran began his martial arts journey at the age of three, initially training in judo. He later expanded his skill set by practicing karate for several years before transitioning to muay Thai at age 14. After dedicating four years to Thai boxing, Duran was introduced to Brazilian Jiu-Jitsu at age 18 by his close friends Caio Ramos and Rafael Cavaca, as well as his uncle Ricardo Duran. Due to scheduling conflicts with university studies and part-time employment, he shifted his primary focus to BJJ, quickly developing a passion for the grappling art. His initial training took place under the guidance of Rodrigo Cavaca, with classes frequently led by then-purple belts Marcus Buchecha and Rafael Cavaca.

Duran swiftly emerged as one of Brazil's most promising competitors during his colored belt progression.

Under Ribeiro's mentorship, Silvio refined his competitive skills and experienced significant growth in his grappling abilities. On November 21, 2016, Duran received his black belt in a ceremony jointly led by Rodrigo Cavaca and Vitor Ribeiro in New York.
