At the World allround championships in Heerenveen on 19–21 March 2010, Kramer won an unprecedented fourth consecutive title. In the general classification after three distances, he ranked number 2, but in the final 10K race he skated 12:57.97 which was more than enough to pass Jonathan Kuck who was leading the overall classification before the start. Kuck ended number 2, Håvard Bøkko third. It also was Kramer's 8th consecutive championship title in European and World allround championship, another unprecedented feat.
