At the FIS Nordic World Ski Championships 2009 in Liberec, Czech Republic, twelve cross-country skiing events were held with six for men and six for women. The format of the program was unchanged since the 2005 World Championships in Oberstdorf, Germany. For the men's events, Norway won five of the six events and a total of six medals with Petter Northug winning golds in the pursuit, 50 km and relay events. Ola Vigen Hattestad won two golds in the sprint events (individual and team). The only event the Norwegians did not win was in the 15 km event (Eldar Rønning was the highest finisher at seventh), won by Estonia's Andrus Veerpalu, who became the oldest world champion ever.
