1900 World Allround Speed Skating Championships
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. 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. Allround results

Rules 
Four distances have to be skated:
 500m
 1500m

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. Silver and bronze medals were not awarded. References
