We saw the Critérium du Dauphiné‘s mountain prologue on TV and it looked pretty tough, but thanks to Velon and GoPro we can now see what it looked like on the bike.

On-board footage is back and several riders strapped a video camera to their bikes before setting off up the daunting Mont Chery in the ski resort of Les Gets and gave us a taste of what they went through.

Annoyingly the viewpoint of the camera means it’s often difficult to tell which rider you are on board with, but several of the shots give you a good indication of just how hard it was.

From the LottoNL-Jumbo rider being overtaken, to another rider furiously changing gears as he went round one of the incredibly sharp corners on the 3.9km route.

Alberto Contador (Tinkoff) won the stage from Richie Porte (BMC) and Chris Froome (Team Sky) to take the first yellow jersey of the race. Not everyone was impressed with the challenging prologue, though, with Tony Martin saying it turned cycling into a “circus”.
