Tour de France 2026 Stage 18: Voiron to Orcières-Merlette

The Tour enters its endgame in the high Alps. Stage 18 climbs 185 kilometers from Voiron to a summit finish at Orcières-Merlette, the opening act of the final mountain trilogy that will decide the 2026 race. After a time trial and a day for the sprinters, the general classification men return to center stage, and with Alpe d’Huez looming twice over the weekend to come, every rider with an ambition in the standings has to commit. There is no holding back now.

The Voiron to Orcières-Merlette route: 185 kilometers into the high Alps

The day works its way deep into the Hautes-Alpes, a long approach that drains the legs before the final climb to the ski station of Orcières-Merlette. It is a steady, demanding ascent rather than a brutally steep one, the kind of finish that rewards a climber with rhythm and deep endurance after a hard day in the saddle. Coming as the first of three consecutive mountain stages, it is also a question of strategy, how much to spend here with Alpe d’Huez waiting twice over the next two days. The bravest will gamble. The cautious may regret it.

Orcières-Merlette, where Ocaña broke Merckx

Orcières-Merlette holds one of the most famous days in Tour history. It was here in 1971 that Luis Ocaña tore the race apart, riding away from Eddy Merckx to win alone and take minutes out of the greatest rider of the age, a ride that briefly looked set to dethrone Merckx himself before fate intervened in the Pyrenees. More than half a century later the climb still carries that memory, a reminder that even the strongest can be broken in the high mountains. To finish a stage here is to race in the shadow of one of the Tour’s defining ambushes.

The first day of the Tour’s final mountain showdown

This is where the Tour is won or lost. The first of three mountain stages in a row, Orcières-Merlette is the moment the general classification battle reignites in earnest, with the time trial having reshaped the standings and the favorites needing to respond. A rider hoping to overturn the race must start his work here rather than waiting for Alpe d’Huez, while the leader has to weigh defense against the danger of being worn down over three relentless days. Whatever happens on the final climb, it sets the terms for the weekend that follows.

Who wins at Orcières-Merlette in 2026?

A long Alpine stage to a steady summit finish suits Tadej Pogačar perfectly, and he will look to take time before the double ascent of Alpe d’Huez even begins. Jonas Vingegaard is the rider most able to resist him and the one most likely to attack in return, a climber who comes alive in the high Alps. Isaac del Toro and Florian Lipowitz are strong enough to hold the leaders deep into the climb, while Santiago Buitrago is a pure climber who can flourish on a long, demanding ascent. João Almeida completes the group, a relentless mountain rider built for exactly this kind of brutal three-day sequence.
