The 7.5 km sprint event was changed to a 10 km individual large hill event while the 15 km individual event was changed to a 10 km individual normal hill event with both  being approved in September 2008.

Norway 's Jan Schmid won a silver in the 10 km mass start and a bronze in the 4 x 5 km freestyle event. A fourth American medal was prevented when Demong was disqualified in the ski jumping part of the 4 x 5 km freestyle team event for failing to wear his bib during competition, dropping the US to 12th and forcing their withdrawal from the cross country portion of the event.
