Stage 18 Breakdown:

Stage 18 takes the riders on a mountainous 185.2km journey from Voiron to Orcières-Merlette. The first stage of the final Alpine trilogy features around 3900m of climbing and marks the return of summit finishes after the time trial and a flat stage. While none of the climbs are exceptionally steep, the accumulated elevation and uphill finish will make it an interesting day for the riders.

The riders begin climbing early with the Côte d’Engins before tackling the Côte de Monteynard and the Côte des Terrasses. The terrain then remains relentlessly undulating as the race heads deeper into the Alps, with the Côte de Saint-Léger-les-Mélèzes softening the legs before the final climb. The climb to Orcières-Merlette is 7.1km at an average gradient of 6.7%. Although not among the steepest summit finishes of the race, it comes at the end of a demanding day and offers plenty of opportunities for the strongest climbers to make the difference.
