Tregubov, among the 169 Russian athletes named on the neutral team which is due to compete at next month's Winter Olympic Games in Pyeongchang, clocked a combined 2min 16.36sec.

The 22-year-old, a bronze medallist at last year's senior World Championships in Königssee, finished 0.93sec quicker than compatriot Vladislav Marchenkov.

Felix Keisinger of Germany came through to take bronze.

The result handed Tregubov a fourth consecutive Junior World Championships title as he continues his preparations for Pyeongchang 2018.

Germany's Anna Fernstädt secured the women's honours as she completed her two runs in an overall 2:20.07.

Russia were denied a clean sweep of the skeleton crowns at the event in the Swiss city as Yulia Kanakina was forced to settle for silver, 0.81 back.

Fernstädt's team-mate Susanne Kreher was the recipient of the bronze medal.

The event is due to resume with the two-man and women's bobsleigh events on Saturday (January 27) following a rest day tomorrow.

Athletes from 22 nations have entered the Championships, which concludes with the four-man bobsleigh competition on Sunday (January 28).
