The reigning world champion and double Olympic gold medallist clocked a combined time of 1min 38.218sec to continue his impressive start to the campaign.

Loch, who led after the opening run, finished 0.285sec clear of nearest challenger and defending overall World Cup champion Roman Repilov of Russia.

Repilov took second ahead of Germany's Johannes Ludwig, who recorded a time of 1:38.919.

Victory for Loch moves him to 655 points, 235 in front of Ludwig in the race for the title.

Tony Eggert and Sascha Benecken of Germany had earlier recorded their third win of the season in the doubles event.

Eggert and Benecken trailed Olympic champions and compatriots Tobias Wendl and Tobias Arlt at the halfway stage before a superb second run propelled them to victory.

The German duo completed their two runs in 1:40.284, 0.141 quicker than Wendl and Arlt.

Thomas Steu and Lorenz Koller of Austria remain in pole position on the overall standings after finishing third.

"We have some catching up to do, especially at the start," said Benecken.

"Overall the performance was already excellent, but it can always be better." 

The women's singles event and the team relay are due to take place when the World Cup resumes tomorrow.
