He has won 4 stages in the Tour de France and the Giro d'Italia, while also claiming a single stage in the Vuelta a España. Konyshev was the first Soviet and Russian rider to win a medal in the Men's Road race at the UCI Road World Championships. He won a silver medal in 1989 behind Greg LeMond, and a bronze medal in 1992 behind Gianni Bugno and Laurent Jalabert. He was also the first Soviet and Russian rider to win a stage at the Giro d'Italia.

He has never won a Cycling monument, but has finished in the top ten on four occasions, three of which were in the Giro di Lombardia. At the 2000 Giro d'Italia, he won both the Points classification and the Combativity classification. During the 1997 edition of the race, he won a stage and the Intergiro classification.

Following his retirement from racing, he became a sports director at Tinkoff Credit Systems. He then moved to UCI World Team Team Katusha in 2009, where he was an assistant sports director for 11 seasons before the team folded in 2019. Gazprom–RusVelo employed Konyshev from 2020 to March 2022, when they lost their UCI license due to the Russian invasion of Ukraine.

Konyshev's son, Alexander Konychev, is also a professional cyclist, although he represents Italy.
