Advanced routes - Alpe d'Huez to Le Croix de Fer
An advanced cyclist route with time trial section that heads north out of Bourg de Oisans
You can buy a microchip for time trail from €3/day.
Go through Allemont towards Lake Verney and then towards Rivier-d'Allemont-Grand Maison. Make use of the long flat stretch along the lake to warm up properly before making the climb up to River.
From the tip of the lake the road rises steeply up to Rivier. From Le Rivier four hairpin bends will take you back down to the stream of l'Eau d'Olle. From its banks you will have a regular but strenuous climb up to the Grand Maison barrage. Now you will have completed the hardest part and will find your rhythm all the way up to the pass.
