At the 1956 Olympic Games in Cortina d'Ampezzo , he set world records in his victories over 500 m (40.2 seconds) and 1,500 m (2: 08.6 minutes). In 1960 at the Olympic Winter Games in Squaw Valley , Grischin won gold again on these two distances, but had to share the medal over 1,500 m with the Norwegian Roald Aas at the same time . As early as 1956 he had to share the victory over this route with his compatriot Juri Michailow and thus achieved a novelty at the Olympic Winter Games in an individual sport that is still valid today. At the Olympic Games in Innsbruck in 1964 , Grischin won the silver medal over 500 m. In 1968 in Grenoble , at the end of his career, he reached a fourth place in the 500 m at the age of almost 37. In 1956 he became European champion in four-way combat.
Yevgeny Grishin set four of his seven world records over the 500 m distance. He held the best performance over 12 years (1956–1968). He was the first runner to undercut the 40-second mark over 500 m. His record time of 39.6 seconds, run in Squaw Valley on February 28, 1960, had not been recognized as a world record. It was not until the end of January 1963 that he achieved a world record on the Medeo track in Alma-Ata, Kazakhstan, with a time of 39.5 seconds, which was officially confirmed by the ISU . This lasted until 1968 when it was undercut by Erhard Keller . From 1955 to 1967 Grischin also held the world record over 1,000 m (1: 22.8 minutes). On this route, Ard Schenk replaced him as the world record holder. He set two more world records over 1,500 m.
