Eloisa Souto competed throughout her career in the Peso Pena division (58.5 kg / 129 lbs), a weight class in which she became one of the most formidable figures on the international circuit. Her brown belt years represented the peak of her colored belt campaign, combining domestic dominance with deep runs at the sport's most prestigious events.
2015: Domestic Titles and a World Final
In 2015, Souto claimed gold at both the IBJJF Rio Winter International Open and the IBJJF Rio Fall International Open, demonstrating her consistency across different competitive formats throughout the year. That same year, she advanced all the way to the final of the IBJJF World Championship in the brown belt Peso Pena division, finishing as runner-up in one of the sport's most competitive events.
2016: Back-to-Back World Finals
Souto returned to the 2016 IBJJF World Championship with clear ambitions of going one step further. Competing again as a brown belt in the Peso Pena division, she reached the final for the second consecutive year, where she faced Danielle Alvarez. Despite falling short in the championship match, her runner-up finish confirmed her standing as one of the elite competitors in her division on the global stage. Earlier that same year, she had claimed the IBJJF São Paulo International Open title, reinforcing her ability to perform across multiple competitive platforms.
Her consecutive appearances in the World Championship final at brown belt — a feat achieved by very few competitors — cemented Eloisa Souto's legacy as one of the standout female competitors of her era in Brazilian jiu-jitsu.
