Allround results* = Fell NC = Not classified NF = Not finished NS = Not started DQ = Disqualified
Four distances have to be skated:
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.
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.
