After victory in yesterday's first HS140/10 kilometres event, Riiber triumphed once more in a time of 29min 27.4sec.

Fellow Norwegian Joergen Graabak was 20.2 seconds behind in the silver-medal position, where he also ranked yesterday.

Rounding off the podium was Germany's Vinzenz Geiger, who was 47.9 seconds back.

That bettered his fourth-place finish from yesterday, while compatriot Fabian Riessle dropped from third to fourth.

Earlier in the day, Riiber had won the jumping event again but only narrowly avoided a crash upon landing. 

Permanent snowfall during the round had accumulated some fresh snow on the landing slope which almost toppled the world champion. 

A jump of 139.5 metres gave Riiber 152.8 points and only a narrow four-second lead over Austrian jumping prodigy Franz-Josef Rehrl, who ultimately ended up finishing in 11th place.

It mattered little to the 22-year-old, though, as he cruised to victory.

Riiber's latest win puts him top of the FIS Nordic Combined World Cup standings with a perfect 500 points.

Graabak remains in second place with 335 points, while Jens Lurås Oftebro completes an all Norwegian top three, despite fifth and sixth-place finishes this weekend.

The FIS Nordic Combined World Cup is due to continue in Ramsau am Dachstein in Austria later this month.

HS98/10 km events are scheduled to be held on December 21 and 22.

"I'm so happy to have five wins in a row, and [to be] having fun in competition," Riiber was reported as saying by Eurosport.

"I'm looking forward to a bit of rest before getting back to it over Christmas."
