From Saint Laurent du Pont, a demanding 14km climb, with many sections at over 10%. It is divided into three parts: 9km of irregular ascent (6 to 11.5% /100m) to the junction for the Chartreuse Monastery. Then 2km of flat terrain to the foot of St Pierre de Chartreuse and finally a very steep climb (several sections at +12% /100m) to the Col de Cucheron. A pass not to be underestimated! 25 degrees at St Laurent = 15 degrees at the top of the pass and its very shaded slopes. Dress accordingly.
