Why This Stage Matters
Another summit finish, now in the southern Alps, and the last big chance for pure climbers before the Alpe double bill. Teams hunting podium spots will throw helpers up the road, while GC leaders rely on whatever support they have left after two brutal weeks.
Stage Highlights
- Col de l’Engins – 11.4 km at 5.4%
- Côte de Monteynard – 9.7 km at 5%
- Côte de Saint-Léger-les-Mélèzes – 2.8 km at 6.8%
- Orcières-Merlette (final climb) – 7.1 km at 6.7%.
The Route
185 km with about 3,950 m up. The stage stair-steps through the Isère valley, over Col Bayard, and ends on the steady 15 km climb to Orcières-Merlette. The final gradient averages 5.9 % but sits at altitude, so oxygen debt builds quickly.
Expert Insight
