Johannes Klaebo Achieves Historic Grand Slam at Nordic Ski World Championships

The Norwegian skier won all six events in Trondheim, becoming the most decorated male cross-country skier in history.

Johannes Klaebo, 28, claimed gold in all six events at the 2025 Nordic Ski World Championships in Trondheim, Norway, a feat never before accomplished in the sport.
The six titles included victories in both sprint and endurance events, ranging from the 1.4 km sprint to the 50 km mass start, showcasing his unmatched versatility.
With 15 career World Championship gold medals, Klaebo surpassed his compatriot Petter Northug to become the most decorated male cross-country skier in history.
Klaebo's triumph occurred in front of 100,000 spectators in his hometown, with the Norwegian royal family in attendance to witness his final victory in the 50 km race.
The achievement cements Klaebo's legacy as one of the greatest in the sport, with comparisons drawn to Russian skier Elena Välbe, the only other athlete to achieve a World Championship clean sweep, albeit in a smaller program in 1997.
