Isaquias Queiroz dos Santos (born 3 January 1994) is a Brazilian sprint canoeist who has competed since 2005.[3] He is the only Brazilian athlete to ever win three medals in a single edition of the Olympic Games, and the third most decorated Brazilian athlete with four medals overall, including a gold medal.
He's been through adversity in his younger years. As a toddler, he poured boiling water on himself and spent a month in the hospital recovering. At the age of 5, he was kidnapped and offered up for adoption before being rescued by his mother, and five years later, he fell out of a tree while trying to catch a snake and lost a kidney.[4][5]
During the 2016 Summer Olympics, Queiroz won three Olympic medals at a single Games: two silver and one bronze. In the C–1 1000 metres event, he finished second, defeated only by Sebastian Brendel, who successfully defended his title. In the process, he became the first Brazilian sprint canoeist to win an Olympic medal. Two days later, he took the bronze medal in the C–1 200 metres event when Yuriy Cheban and Valentin Demyanenko were faster than him. Together with Erlon Silva, they won the silver medal during the last day of canoe sprint competitions in the C–2 1000 metres category. Queiroz was the first Brazilian athlete in history to win three medals at a single edition of the Olympic Games and the first sprint canoe athlete from any nationality to do so in the history of the Olympics.[7]
The 2020 Summer Olympics had Queiroz partnered with Jacky Godmann as Erlon Silva had not recovered from a hip injury. In the C–2 1000 metres category, Queiroz and Godmann finished in fourth place. Queiroz won the gold in his remaining race, the C-1 1000 meters. He considered a consolidation of extensive training to get a victory that eluded him in Rio and became the first Brazilian Olympic champion in canoeing.[5]
