Stage favourites

Stage 20 (Bourg-d'Oisans → Alpe d'Huez, 170.9 km) is a mountain stage with 5,601 m of cumulative climbing — one of the race's queen stages. Pure climbers capable of sustaining high power output on long ascents are the ones to watch.

⚡ The real race begins on the final climb. Any rider distanced before the summit will lose significant time on GC rivals.
