Even the ranking points of concurrent skaters can be strongly affected by the opportunity skaters have to train and compete on fast rinks. For example, before the 1960s, skaters were dependent on long periods of frost, less common at more southerly latitudes. The effect of access to high altitude rinks was especially notable from 1973 to 1986, when most world records were set at Medeo in Kazakhstan, a rink at 1,691 m that also enjoyed an unusual all-around tailwind, but was rarely accessible to non-Soviet skaters. In 1977–78, the Adelskalender top 10 consisted almost entirely of times set at Medeo, while several skaters in the top 10 never reached the podium at international meets. Currently, the two fastest speed skating rinks are, by a long way, the high altitude covered ovals at Calgary and Salt Lake City, both in North America. Indeed, after the 2014–15 season, 65 of the last 67 new world distance records and the 264 best times ever on the men's 1000 m were recorded at one of these two venues.
