Cross-country skiing-Johaug dominates women's 30km to win Norway's 16th gold

ZHANGJIAKOU, China : Norway's Therese Johaug powered to victory in the final race of her Olympic career, winning the women's 30km freestyle mass start in a display of enormous strength and discipline and netting her third individual gold of the Beijing Games.

American Jessie Diggins came in second 1:43.3 behind Johaug to collect the silver medal, with Kerttu Niskanen of Finland making a late burst to take the bronze.

Diggins had to be carried from the finish line, one of many racers overcome by the cold and exhaustion.

However, none of that could dispel Johaug's joy as she closed out her Olympic career with a gold - her nation's 16th of the Beijing Games and a record for a single country at a Winter Olympics.

The race was moved forward by three-and-a-half hours as once again high winds whipped through the mountains in Zhangjiakou at speeds of up to 15 km per hour over the four 7.5km laps, but the Norwegian was undeterred.

Johaug wasted no time getting out in front, taking control after the first 2km and stretching the field out with Sweden's Ebba Andersson shadowing her in a breakaway group of seven racers that was quickly reduced to four.

France's Delphine Claudel battled gamely to hang on to the leaders but they were soon whittled down to a trio, and Johaug took her chance just before a third of the race had elapsed.

As Andersson briefly paused for a drink around the 9km mark, Johaug spotted her opportunity and made another break, dropping the Swede and leaving the leader with only Diggins on her tail, but the American sprint specialist could not reel her in.

Johaug's lead over Diggins was soon up to 27 seconds and she pressed on relentlessly, occasionally looking behind her but only seeing the snow being whipped across
