The six-time World Cup leader has built a substantial lead of 0.53 seconds over Russia's Olympic gold medallist Alexander Tretiakov.

His position was strengthened further as his third run time of 52.11sec bettered his best performance from the opening day by 0.03 seconds.

Dukurs, who shared the European Championship title with his brother earlier this month, completed the competition in style by clocking a time of 52.09.

His combined total of 3min 28.84sec saw him comfortably claim the world title for the fourth time in his career.

Having claimed his country’s first World Cup win at St Moritz on February 5, South Korea’s Sungbin Yun had vowed to attack the World Championships as he continues to build towards a home Winter Olympics at Pyeongchang in 2018.

The 21-year-old continued to show his potential by posting times of 52.37 and 52.41, as he aimed to improve from his third place position after the opening day.

His efforts were rewarded with a silver medal he shared with Tretiakov, who also ended the competitionwith a combined time of 3:29.97.

A bronze medal was not awarded due to the silver being shared, resulting in Germany’s Axel Jungk missing the podium having clocked 3:30.71 to end fourth.

Germany could be celebrating success in the women’s event, however.

Tina Hermann leads at the halfway stage after finishing the first two runs in a time of 1:48.34.

Her nearest challenger,Austria's Janine Flock, is currently 0.15 seconds off the pace heading into the final day of the competition.

Another German, Sophia Griebel, leads the race for the final podium position.

Her time of 1:14.87 sees her lying just 0.01 and 0.02 ahead of the United States’ Anna O’Shea and Russia’s Elena Nikitina.
