Norway has long stacked the field with champions in Nordic skiing and sailing, but a new generation of athletes has arrived on the endurance scene, smashing records and grabbing medals in running, triathlon, and cycling. Sports journalist Brad Culp explores the role of culture in the unexpected rise of the "Norwegian method," beginning with the Vikings that turned the open seas into superhighways, and more recently, the emergence of well-funded sport schools and Olympic programs that serve as a pipeline of elite performers. Get to know the athletes, coaches, and scientists behind the method that entails banking years of high volume at low intensity, and the celebrated double-threshold workouts that are dictated by blood lactate testing. Years of mega-volume and controlled intensity, coupled with meticulous altitude and heat training, have added up to a trove of medals across a number of sports. With a decades-long track record of turning workhorses into winners, the Norwegian method is upending long-held beliefs about endurance training and redefining the limits of human performance. Culp weaves an inspirational story while also supplying a blueprint for how endurance athletes can adapt their own training and lifestyle to look more like that of Norway's greatest champions-Jakob Ingebrigtsen, Kristian Blummenfelt, and Gustav Iden, who have combined to win four Olympic gold medals and eight world championships ... and counting.
