Norway’s Vetle Sjaastad Christiansen took control of the Oestersund men’s 15 km mass start after cleaning the first prone stage, skiing unchallenged to his first individual victory of the season in 35:17. The win put Christiansen, the only man in the field to shoot clean atop the podium for the third time in the last week after a men’s relay win yesterday and a single mixed relay last Sunday in Nove Mesto na Morave.
