A classic climb from Aiton , well known to local cyclists.
Even if it's not very long, it's still demanding on the first part of 5.4km to the route des Combes as the average percentage is 8.2％ , the gradient is always between 7.5 and 8.5％ sometimes above, I didn't meet the 100M at 16.8％.
There are then 2km of slight downhill and then the last 500m a little steeper to reach the heart of the small village of Aiton.
To get a magnificent view of Les Bauges just opposite and the valley, push on behind the Church.
Une montée classique au départ de Aiton , bien connue des cyclistes locaux.
Même si elle n'est pas très longue, elles reste exigeante sur la première partie de 5,4km jusqu'à la route des Combes puisque le pourcentage moyen est de 8,2％ , la pente est toujours entre 7,5 et 8.5％ parfois au dessus, je n'ai pas rencontré les 100M à 16,8％.
Il reste ensuite 2 km en légère descente puis les 500 derniers mètres un peu plus pentus pour arriver au cœur du petit village de Aiton.
Pour avoir un magnifique point de vue sur Les Bauges juste en face et sur la vallée, poussez jusque derrière l'Eglise.
