Boucle Cyclosportive B1 - La Route des 4 Cols

Actual departure from Archettes, but this loop passes through Gérardmer.
This loop is designed for sporty cyclists. From Archettes, you cross the Moselle to reach Arches, where the signposts lead you along a hilly, shady road to Remiremont. Be careful approaching the junction with Route Nationale 57, where traffic is heaviest. You pass through Remiremont, skirting the railroad line and then the lake. You then follow the left bank into the Moselotte valley as far as Vagney. This is where the mountain section begins, with 4 cols in succession: a demanding 28-kilometer route that follows the route of the 2014 Tour de France. From La Mauselaine, take the Dix-Sept Kilomètres (*) forest road back to the center of Gérardmer. After a good descent, you can recuperate by skirting the lake before returning to Vagney via the last pass and then Archettes via the right bank of the Moselle.
Variant: for purists wishing to follow in the footsteps of the Tour de France pros, on leaving La Bresse on the Col de Grosse Pierre, turn left onto the Chemin de la Roche for 3 kilometers (7.5% average gradient, with one section at 16%).
