The International Winter Sports Week in Chamonix, retro-actively dubbed the 1924 Winter Olympics, contained five speed skating events. Uncommon for the time, it not only included an all-round competition, but also awarded medals for the individual distances: 500 m, 1500 m, 5000 m and 10000 m. The all-round event was dropped before the 1928 Games, even though it remained the only World Championship format in the sport until the 1970s; single distance World Championships were not established until 1996.
The 1932 speed skating events were held according to the North American rules, meaning the skaters competed in small packs of skaters (the format paved the way for the development of short track speed skating), instead of the common against-the-clock format. These Games in Lake Placid, New York, also saw the first female speed skaters at the Olympics in a set of demonstration events, with all victories being achieved by North American athletes. Women's events were also set to be held at the 1940 Winter Olympics,[1] which were cancelled. After the war, they were withdrawn again by the decision of the IOC until the 1960 Olympics in Squaw Valley, when the women skated 500 m, 1000 m, 1500 m and 3000 m.
Following the introduction of World Sprint Championships in the early 1970s, the 1000 m for men was added in Innsbruck 1976, while the women's 5000 m, reinstated by the ISU as an official distance in 1981, made its Olympic debut in 1988. The latest addition to the Olympic speed skating programme is the team pursuit, which was added for the 2006 Turin Games. Its inclusion was remarkable as it had not yet been contested at a senior World Championship in the form skated at the Olympics at the time of inclusion. It had however been contested at a senior World Championship, the Dutch team won the 2005 title in Inzell, but in that form they only had to skate once and be the fastest, while the Olympic form required three starts.
