Björgen - the world's best cross-country skier of all time was an expert at Norwegian TV2 during the Tour de Ski, thought that Frida Karlsson's tactics were suitable for the Americans who during the whole race could be behind the Swede when she chased leading Linn Svahn.

-You could see that Frida wanted a high tempo and pulled in three of the four laps.

You learn as long as you live.
