Northug has won almost everything the sport of cross-country skiing has to offer – Olympic titles, World Championship titles and the overall World Cup crown.
He even has the most Tour de Ski stage wins but he is yet to claim the overall title having finished second three times and third over the past four years.
This season’s Tour de Ski could be Northug’s though as the Norwegian once again proved his dominance in the 4km freestyle prologue to win by six seconds.
Northug clocked a winning time of 8 minutes 28.7 seconds as the mist cleared following the women’s race in Germany although wet conditions allowed for slushy snow.
That affected Northug little, who after taking the opening stage last year did so again on stage four but had to make do with third as Dario Cologna won overall.
Marcus Hellner, runner-up to Cologna last year, led until Northug crossed the finishing line with the Swede 6.1 seconds behind his Norwegian rival in second.
Alexander Legkov was third a further 1.1 back in third while defending champion Cologna was fourth with the 15km classic pursuit to come on Sunday.
