Norway earned a clean sweep in the short individual events as Tiril Eckhoff and Johannes Thingnes Bø defied the freezing conditions to claim victories in the men's and women's events at the International Biathlon Union World Cup in Canmore.
Eckhoff clinched her first individual victory in a time of 36min 32.9sec on a course shortened by event organisers owing to fears over the weather conditions in the Canadian town.
The five-time Winter Olympic Games gold medallist, who amassed one penalty, finished 9.8 seconds in front of the Czech Republic's Markéta Davidová, who took home silver.
Italy’s Lisa Vittozzi won the bronze medal as she crossed the line 20.9 seconds behind the triumphant Norwegian.
Vittozzi's result saw her close the gap to overall leader and compatriot Dorothea Wierer to just five points.
Wierer, who could only manage 22nd today, has 651 points, with Vittozzi second on 646.
"I was a little bit emotional because I never thought I would win an individual," Eckhoff said.
There was a familiar winner in the men's event as Bø strengthened his advantage at the top of the standings by securing victory in the first short individual competition to be held as part of a World Cup.
The reigning OIympic 20 kilometres individual champion reigned supreme over 15km, earning his 12th win on this year's World Cup circuit in a time of 35:27.9.
Vetle Sjaastad Christiansen added to the Norwegian success in Canmore as he claimed the silver medal, while Russian convicted drugs cheat Alexander Loginov did enough for third.
Bø suggested the 15km individual race should replace the 20km event on the World Cup calendar following his victory in the Canadian resort.
"This has been quite different week from other World Cups because of the cold," he said.
"This was the first day I was in race mode.
"It was fun to get back on the tracks to compete.
"I really liked it; I think it is a better race; more tight and fun to watch for the spectators and I think this is the last year for the 20km."
Bø now has a total of 896 points, 300 more than nearest challenger Loginov, while French star Martin Fourcade is third.
Organisers are hopeful the full programme of events can be held in Canmore, despite concerns over the plummeting temperatures and the event is set to continue tomorrow with the men's and women's relay races.
