Today marked the first mountain stage in the Tour de Suisse, with one Category 1 climb and a summit finish on a HC climb. The stage started at an incredible pace, which made that a breakaway of four riders was only formed after twenty kilometres. The peloton gave Boom, Duchesne, Van der Lijcke and Warbasse a maximum lead of eight minutes. Tim Wellens tried to bridge the gap to the four leaders, but stranded at twenty seconds and eventually dropped back to the peloton. At the start of the final ascent, the leaders had an advantage of four minutes on the peloton, but Warbasse quickly left the other escapees behind. The peloton also increased its pace on this climb and a group with six GC contenders escaped in chase of the sole leader. In the end, they failed to catch Warbasse, who finished the stage with a forty-second advantage on Damiano Caruso and Steven Kruijswijk. Caruso is the new leader in the GC. Bart De Clercq finished in twentieth place, 2’49” behind the stage winner.
