1912 World Allround Speed Skating Championships

Nikolay Strunnikov was defending champion but did not take part in these championships. Oscar Mathisen had the lowest number of points awarded and won all four distances. He became World champion for the third time. He and Jaap Eden are the only ice-skaters winning the World championship three times (so far). Allround results

Rules 
Four distances have to be skated:
 500m
 1500m
 5000m
 10000m

The ranking was made by award ranking points. The points were awarded to the skaters who had skated all the distances. The final ranking was then decided by ordering the skaters by lowest point totals. 1 point for 1st place
 2 point for 2nd place
 3 point for 3rd place
 and so on

One could win the World Championships also by winning at least three of the four distances, so the ranking could be affected by this. Silver and bronze medals were awarded. References
