Petter Northug, Norwegian skier

Petter Northug Jr. is a Norwegian former cross-country skier and double Olympic champion. He won a total of 13 World Championship and two Winter Olympic gold medals with 20 medals overall, and 18 individual FIS Cross-Country World Cup wins with 13 podium places. He is also the record holder for most stage wins (13) in Tour de Ski. By winning his ninth gold medal in the Nordic World Ski Championships in 4 × 10 km relay in Val di Fiemme 2013, he leveled the achievement of Bjørn Dæhlie who had been the most successful World Champion male skier up to that point. He is considered by many as the greatest cross-country skier of all time.
