Organisers had been forced to shorten the stage, with 22.3 kilometres taken off the start as the risk of snow saw them remove the opening descent from Champéry.

Racing would begin in the valley in Aigle, with the peloton set to complete a distance of 136.5km to the finish in Bulle.

Local rider Küng would feature in the day’s key move, breaking away with Ukraine’s Andriy Grivko and the Belgian duo Frederik Veuchelen and Sander Armée.

The four-men attacked in the early kilometres of the stage and the peloton would prove unable to catch all the riders in the break.

Küng and Grivko would ultimately contest a sprint finish for the victory, having dropped their breakaway companions on the day’s final climb in Bulle.

The Swiss rider would come out on top in the head-to-head battle, winning the stage in a time of 3 hours, 33min and 15sec.

Both riders were awarded the same finishing time, while the peloton would cross the line with a 20sec deficit to the leaders.

The result would not change the general classification, with prologue winner Fabio Felline of Italy remaining out in front.

The Trek-Segafredo rider is eight seconds clear of his nearest challenger Maximilian Schachmann of Germany and Spain’s Jesus Herrada.

Slovenia's Primoz Roglic is the highest placed of the pre-race favourites at nine seconds off the lead.

Britain’s Chris Froome, the 2013 and 2014 winner, remains 29sec behind the race leader.

BMC Racing team-mates Richie Porte of Australia and the United States' Tejay Van Garderen are 33 and 34sec off the pace respectively.

The International Cycling Union (UCI) WorldTour race will continue tomorrow with a 187km flat stage from in Payerne.
