Isabel Grevelt skates to the third fastest time with 38.02. The winner of the 1000 meters on Saturday thus retained the lead in the rankings. A second 1000 meters will follow on Sunday. Grevelt has a lead of 0.22 seconds over Marrit Fledderus. Dione Voskamp is third.

Marrit Fledderus comes first with 37.75. Voskamp records the second time (37.90). The skaters compete for the last ticket for the World Cup sprint. Jutta Leerdam and Femke Kok have already qualified for the World Cup and are not present in Heerenveen.
