Stage 8 will be the longest of the Tour with 224 kilometers, a hilly day suited to the breakaway specialists into Le Creusot. In the Jura, the peloton will find its first day in the high mountains on stage 9, with a summit finish on the Grand Colombier.
Tadej Pogacar and Remco Evenepoel will have over 70 kilometers of time trials at the 2027 Tour de France
Sallanches headlines the Alps
The second week of the Tour begins in the Alps with an explosive stage into Sallanches - which will later host the World Championships. The riders will find several steep climbs, including the mythical Côte de Domancy.
Stage 11 from Cluses to Les Saisies is the second day in the Alps, the shortest of all stages at the Tour aside from the time trials and the final day in Paris. It will however feature plenty climbing with the Col de la Colombière, Col du Pré and Montée de Bisanne all on the course.
Stages 12 and 13 are opportunities for the sprinters into Valence and Montpellier; whilst stage 14 sees the summit finish on the Côte de la Croix Neuve after several difficult ascents in the Massif Central. Stage 15 to Albi ends the second week with an opportunity for the sprinters.
A second big time trial and Pyrenees showdown
The Tour de France has changed its formula and the final week will open up with a 33-kilometer long time trial in Toulouse, mostly flat but with a short and steep ascent that should prove spectacular. Combined, the two time trials total up to 71 kilometers against the clock, the most since the 2012 Tour. Stage 17 finishes in Pau where the sprinters will have another go.
Stage 18 will be the first in the Pyrenees, the race's toughest day with around 5300 meters of climbing. The riders will tackle the Col du Soulor, the Col du Tourmalet, the Hourquette d'Ancizan and then a summit finish on the Col du Portet - 16 kilometers long at 8.7%.
Stage 19 will be the final day in the mountains, without a summit finish but with the steep ascents of the Col du Burdincurutcheta; the Col de Soudet and the Col de Marie Blanque, before the arrival to Lauruns.
The race finishes with stage 20, a sprinter day in Libourne; and stage 21 in which the cobbled ascent to Montmartre makes its return once again to make for an explosive finale in Paris.
