The course is fairly flat. Yet at kilometre 1.5 a 400 metres hill at 6% leads to a short drop and a false flat (3%) sector of 300 metres. It is there the riders hit the highest point in the route at an elevation of 450 metres, while the lowest point sits at 404 metres.
Last year’s Tour de Romandie started with a more hilly prologue. Ion Izagirre powered to victory ahead of Tom Dumoulin and Michal Kwiatkowski.
The UCI is based in Aigle. The town of 8,000 is used to visiting pro-cycling pelotons. The 2014 Tour de Romandie saw a sprint-à-deux in its streets with Simon Spilak besting Chris Froome. On June 13th stage 4 in the Tour de Suisse passes through Aigle before hitting the closing climb to Villars-sur-Ollon.
