A stunning second lap by Norway's Ragnhild Haga propelled her to Olympic gold in the women's cross-country 10-km freestyle race in a time of 25 minutes, 5 seconds on Thursday.

Charlotte Kalla of Sweden took silver, more than 20 seconds adrift, while Marit Bjoergen of Norway and Finn Krista Parmakoski dead-heated for the bronze medal.

Kalla, who won the women's skiathlon on Saturday, began the race as odds-on favorite for a second Pyeongchang gold and started powerfully, immediately taking the lead from Bjoergen at the first split time.
