Cross-country skiing has been a means of transportation for thousands of years in Scandinavia, but formal ski races were not held until the mid-1800s in Norway. Cross- country skiing was part of the very first Winter Olympics but women did not compete in cross country events until 1952. Cross country skis are narrower and lighter than Alpine (downhill) skis and special bindings allow the heel to lift with each stride. Poles, too, are longer and lighter than those used in downhill skiing. There are currently six women's and six men's events in Nordic skiing, including a relay race, and for men only, a combined event featuring skiing and ski jumping. Norwegians, Finns and Swedes dominated cross country events, winning every Gold, Silver and Bronze medal until 1956, when the Soviet Union joined the Games. The Soviet women in particular have been very strong. The East Germans also had great success in the 1970s. The U.S. has won only one medal in cross-country events, when William "Bill" Koch captured a Silver in 1976 at Innsbruck. In both the 1992 and 1994 Winter Olympics, the Italians made a very strong showing, breaking the Soviet (now Russian) and Scandinavian domination in these events.
