She took a her 10 second advantage into the second stage of the competition and extended her lead to 61 seconds in the women's pursuit race.

She completed the 10 kilometres course in 29min 27.6sec to strengthen her advantage over second-placed Heidi Weng, with an all Norwegian top three being completed by Therese Johaug.

Norwegian dominance continued in the men's competition as Petter Northug claimed victory in the 15km pursuit event, ahead of Canada's Alex Harvey and Calle Halfvarsson of Sweden.

Northug leads the event by five seconds after completing the pursuit event in 42:01.2.

Switzerland's three-time Tour de Ski winner Dario Cologna is further back in sixth place.

"I tried to stay in the leading group," said Northug after the stage.

"There was a lot of fighting for positions.

"It was better for me stay little bit back and save energy for the last lap."

The Tour is scheduled to resume on Tuesday (January 6), in Cologna's native Switzerland, with a free technique sprint competition.

The event is due to conclude on Sunday January 11 with a pursuit in Val di Fiemme, Italy.
