The World Single Distances Speed Skating Championships are a series of speed skating competitions organised by the International Skating Union.
The ISU Speed Skating World Cup is a series of international speed skating competitions, organised annually by the International Skating Union since the winter of 1985–86. Every year during the winter season, a number of competitions on different distances and on different locations are held. Skaters can earn points at each competition, and the skater who has the most points on a given distance at the end of the series is the winner. Initially not very popular with skaters nor spectators, the World Cup has gradually become more and more popular, and this was due to the creation of the World Single Distance Championships. The results of the separate distances in the World Cup ranking are the main qualifying method for the World Single Distance Championships.
