Norway's Heidi Weng and Sergey Ustiugov of Russia both claimed overall Tour de Ski titles as the stage race finished with a nine kilometre pursuit climb at Val di Fiemme in Italy.

Weng claimed her first win of this year's Tour and has now become the only female winner of the event with less than two stage victories.

Prior to today's race Weng was 19.2 seconds behind Sweden's Stina Nilsson, but that deficit was quickly chalked off.

Weng powered away from the rest of the field to claim a clear victory in a time of 33min 34.3sec.

Finland's Krista Parmakoski also finished in front of Nilsson as she crossed the line in second, 1:37 behind Weng in 35:30.5.

Nilsson rounded off the top three in a time of 35:47.9, almost two minutes after Weng which handed victory to the Norwegian.

Today's podium mirrored the overall rankings as Weng claimed the title with an overall time of 2:27:39.4.

Parmakoski finished second in the Tour in 2:29:16.4 while Nilsson, who led at the start of the day, took third place in 2:29:33.8.

Ustiugov, meanwhile, breezed to victory in the men's Tour de Ski after impressively winning six of the seven stages.

The Russian finished just over a minute in front of Norway's Martin Johnsrud Sundby who took second place.

He crossed the line first in today's pursuit in a time of 30:27.7.

Sundby took second in 31:30.6 while Switzerland's Dario Cologna completed the podium in 31:46.8.

Ustiugov finished in first place overall in a time of 3:24:47.9, while Sundby followed behind in 3:25:50.8.

Cologna rounded off the podium in third on 3:26:07.0.

The Tour de Ski forms part of the International Ski Federation (FIS) Cross-Country World Cup season, which will resume in Tolbach in Italy on January 14.
