ROAD BIKE ON THE COL DU GLANDON
We normally start the Col du Glandon from the Maurienne Valley and often include it on our Alpe d'Huez day. The start is about a 70 minute drive from our Chalet Grange a Charlotte in Les Allues.
The first 8kms is a steady 6-8% climb before reaching a flat 2km section. After the flat, the next 7kms are a bit steeper with some sections getting up to around 9%. The last 3kms are very tough averaging 10%,11% and 10%.
It is possible to combine this with the Col de la Madeleine
as seen in the 2012 l'Etape cycle sportive.
