Norwegian skier sees a "frightening development" in traditional cross-country skiing. "The audience disappoints when the product is not exciting," says Northug.

Northug: "I don't think it will take over, but I think the ski family is so small that you would benefit from working together" "It's an advantage for Ski Classics, it's very inclusive. It's a good place to start," he says of the long-distance race cup. "I think it's good for the sport to have a long-term future," Northug says.
