Stanisław Styrczula joined WKS Zakopane in 1950 and, the following year, became a national champion in biathlon’s 4x10 km relay. He followed this up with a second-place national finish in the Nordic combined in 1952 and another 4x10 km title in 1954. His first major international tournament was the inaugural 1958 Biathlon World Championships, where he finished in fourth in the 20 kilometer team event alongside Stanisław Szczepaniak and the non-Olympians Stanisław Zięba and Stanisław Gąsienica-Sobczak. Styrczula also competed at the 1961 and 1962 editions, but did not reach the podium. His final appearance came at the 1964 Innsbruck Olympics, where he was 35th among 51 entrants in the 20 km. individual event. He retired from active competition after the Games, but later worked as a skiing instructor and judge.
