Sweden’s Hanna Öberg won the season-ending women’s mass start race at the International Biathlon Union World Cup as Italy’s Dorothea Wierer was crowned as the overall champion.

Öberg was yet to earn a World Cup victory in her career, despite being the reigning Olympic and world champion in the individual 15 kilometres event.

The 23-year-old was able end her wait by edging a tightly fought battle with Norway's Tiril Eckhoff.

Öberg received two shooting penalties during the 12.5km event at the Holmenkollen Ski Stadium, but crossed the line in a winning time of 35min 56.2sec.

She ended 1.3 seconds ahead of Eckhoff, who was left to rue the three penalties she received during the race.

United States’ Clare Egan secured a maiden podium finish, ending 10.4 seconds behind the winner.

The result also saw Öberg receive the mass start crystal globe.

The overall World Cup crystal globe was awarded to Wierer, who came the first Italian to end with the top score at the end of the season after accruing 904 points.

Her team-mate Lisa Vittozzi finished second on 882 points.

The men’s 15km mass start event saw Norway's Johannes Thingnes Boe conclude his superb season in style.

Boe, who was already assured of the overall World Cup title, earned his 16th win of the season.

He shot clean on route to winning the event in 37:25.6.

Germany’s Arnd Peiffer and Benedikt Doll completed the podium, after ending 19 and 32 seconds back respectively.

Boe ended the season with a clean sweep of World Cup titles, having topped the sprint, pursuit, mass start and overall standings.
