The prolific Francesco Friedrich added European Championship gold to complete his four-man title collection with victory in Winterberg, Germany.
The two-man and four-man Olympic champion has dominated the two-man season so far with victory in all but one race, and he continued this terrific form in the opening big sled race of the season.
Alongside Alexander Schueller, Thorsten Margis and Candy Bauer, the German team got off with a bang in their second run with a new Winterberg start record of 4.96 seconds.
