The 1900 World Allround Speed Skating Championships took place at 24 and 25 February 1900 at the ice rinks Frognerkilen in Kristiania (Today: Oslo), Norway.[1] The first day was skated at the ice rink Friedenauer Sportplatz (a 400 m ice rink). Due to the bad ice conditions the second day the distances were skated at the ice rink Westeisbahn (a 335 m ice rink).
Peder Østlund was the defending champion, after 2 distances he stopped.
Edvard Engelsaas won three distances and became the new World champion.
One could only win the World Championships by winning at least three of the four distances, so there would be no World Champion if no skater won at least three distances.
