Stage 20 of the 2026 Tour de France runs 171km from Le Bourg-d'Oisans to Alpe d'Huez. Le Bourg-d'Oisans to Alpe d'Huez spans 171km and the official route notes confirm the south-eastern ascent of the Col de Sarenne before the final return to Alpe d'Huez.
Route and profile
That design makes this a more tactical final mountain stage than a simple summit-finish repeat. The route should reward teams that still have riders to launch moves before the last climb. Officially this is a mountain stage, and that profile should shape the way teams approach the final hour.
How the stage is likely to race
If the Tour is still within striking distance, this is the final place to force a collapse. Breaks can go long, but the biggest names should still end up deciding the stage if the jersey gap is narrow.
Likely winner archetype
A climber with the endurance for repeated Alpine efforts and the nerve to race before the final ascent.
Prospective winners
Based on the current preliminary startlist picture, the main names to watch are Tadej Pogacar, Jonas Vingegaard, Juan Ayuso, and Ben Healy.
