Russian sprint canoeist Sergey Galkov started his career under the guidance of his father, Vitaly, who won a bronze in the sport at the 1968 Mexico City Olympics. Sergey soon joined Dynamo Moskva, becoming a multiple-time USSR champion in the late 1980s. In 1988 he competed in the K2 1,000 metres with Siarhei Kalesnik at the Seoul Olympics, with the pair reaching the semi-finals. Galkov then won medals at the Canoe Sprint World Championships; first with bronze in the K4 500 metres (with Oleg Goroby, Sergey Kirsanov, and Andrey Plitkin) in 1991, with another bronze two years later in the K4 10,000 m (with Sergey Verlin, Vladimir Bobreshov, and Georgy Tsybulnikov). Galkov later served as the President of the Moskva Kayak and Canoe Federation.
