Sweden's Frida Karlsson crossed the line first in the women's 10-kilometre interval start classic race today to take the lead in the Tour de Ski standings after three races; while Norwegian Johannes Høsflot Klæbo won his third race from three in the tournament.

It was the first of two legs in Oberstdorf, with the Tour de Ski covering seven legs of the International Ski and Snowboard Federation (FIS) Cross-Country Ski World Cup.

Karlsson took the lead in the women's overall classification with victory today in a time of 24min 53.3sec ahead of Finland's Krista Pärmäkoski, who trailed by 16.1 seconds.

Anne Kjersti Kalvå pipped Norwegian compatriot Tiril Udnes Weng to the bronze, 18.1 seconds behind the winner, while a second Finn, Kerttu Niskanen, completed the top five.

Karlsson now has a 20-second gap to Weng in the standings, followed by Kalvå by the same deficit.

Niskanen is fourth, 41 seconds back.

Klæbo remains dominant in the men's race, winning again to extend his lead to 37 seconds.

Today he was top of an all-Norwegian podium in a time of 21:38.5 - 12.4 seconds in front of Simen Hegstad Krüger, who was a further 10 in front of Didrik Tønseth.

Sweden's Calle Halfvarsson was the only non-Norwegian in the top five, followed in by Pål Golberg.

Golberg's lower finish made the gap 37 seconds overall to Klæbo, with Krüger three more seconds back in third going into tomorrow's 20km pursuit freestyle.
