Starts at the round about near the Lac de Carouge. The first 4 km are moderately steep (mostly 5-7 %) and wind first through agricultural land and then through the diverse settlements of Saint Pierre d'Albigny. At the last settlement the steepness increases up to 7-8 %, which sets the standard up to the pass, which is reached after a total of 9.9 km and 670 elevation meters. The climb is popular among race bikers, which are probably mostly local. There is little traffic and road conditions are good.
