Stage 14 of the Tour de France 2026: a fierce mountain test between Mulhouse and Le Markstein

Mulhouse sets the tone with an immediate ascent

Mulhouse returns to the Tour de France for the 18th time, and it wastes no time challenging the peloton. Within minutes of the start, riders will hit the lower slopes of the Grand Ballon via Uffholtz. At 21.5 kilometers long with a 4.8 percent average, it is not the steepest climb — but as the first col of the day, it ensures early tension and makes for a brutal warm-up.

This early effort will test team strategies. Should a breakaway form here, it will likely contain strong climbers, not opportunists. With such a stacked climbing menu to follow, only serious legs will survive the day.

Main climbs on stage 14 between Mulhouse and Le Markstein

Col du Haag: the wildcard climb that could define the Tour

While many climbs on this stage are familiar, the Col du Haag is a new and terrifying addition. Hidden deep in the forest above Saint-Amarin, this 11.2 km ascent averages 7.3 percent, with savage pitches reaching 15 percent. The road is narrow, irregular, and almost never flat — a pure climber’s playground and a director sportif’s nightmare.

With the summit just six kilometers before the final run to the finish, the Col du Haag could explode the race. Riders who go into the red here may not recover in time for the final ascent. Conversely, a decisive attack could create critical gaps before the final showdown at Le Markstein.

Le Markstein returns for a spectacular mountain finish

Le Markstein is no stranger to Tour drama. In 2023, it was the backdrop for a legendary duel between Pogačar and Vingegaard. This time, riders will tackle it twice — once mid-stage, then again as the final summit finish. The second approach, after a full day of climbing, promises to be decisive.

The climb itself is not excessively steep, but context is everything. After hours of effort and with tired legs, the final six kilometers to the finish could be brutal. With wide-open roads and alpine winds sweeping across the ridgeline, the scene is set for a mano-a-mano battle between the yellow jersey contenders.

General classification shake-up likely on stage 14

With only one rest day and one full mountain week remaining after this stage, stage 14 offers a rare early opportunity for GC riders to test each other. The density of climbs and the unpredictable nature of the Col du Haag mean that no one can hide. One bad moment could lead to minutes lost, while a brave move could lead to a Tour-defining gain.

Teams with strong mountain domestiques will be crucial early on, but in the final 10 kilometers, it will be every leader for themselves. The best climbers will rise. The vulnerable may fall out of contention entirely.

A showcase for cycling in the Vosges and Grand Est

Beyond the race itself, stage 14 is also a celebration of the Vosges. Often overshadowed by the Alps or Pyrenees, this mid-mountain range offers equally thrilling climbs, dense forests, and stunning panoramas. Towns like Saint-Amarin and Saint-Maurice-sur-Moselle bring local charm, and the entire region is a dreamland for cyclists seeking quieter, challenging roads.

For cycling tourists, following this route means combining heritage with sport — from Mulhouse’s industrial history to the high-altitude landscapes of Le Markstein. Whether you’re chasing KOMs or just soaking in the view, this part of France delivers.
