So, the last three weeks not much more became clear, although we had some extra rumours. New additions are bolded. One week to go.
With Eshnar's assesment (***** = certainty; * = wild guess):
Stage 1: Noirmoutier-en-l'Île - Fontenay-le-Comte; flat (*****)
Stage 2: Mouilleron-Saint-Germain - La Roche-sur-Yon; flat (*****)
Stage 3: Cholet - Cholet: ttt (*****)
Stage 4: La Baule - Sarzeau; flat (****)
Stage 5: Lorient -
Quimper: flat with
ribins (other than those of tro Bro Leon) (****)
Stage 6:
Brest -
Mur de Bretagne: with the hilltop finish(***)
Stage 7: Fougères - Alençon: possibly with a hilly final (4-5 hills from 40km to go to 15km to go, crossing the so-called
Alpes Mancelles) (****)
Stage 8: Dreux - Amiens; flat (****)
Stage 9:
Arras - Roubaix; rumours about a few cobble sectors (***)
restday + transfer to the Alps
Stage 10:
Annécy - Le Grand Bornand; high mountains, Plateau des Glières,Romme + Colombière? (****)
Stage 11:
Albertville - La Rosière; high mountains + mtf (***)
Stage 12: Bourg-Saint-Maurice - l'Alpe d'Huez; high mountains (Madeleine-Glandon-traditional mtf or Madeleine-Galibier-Sarenne) (***)
Stage 13: Bourg d'Oisans - Valence; (****) start and finish seem to be decided, question is what will be the course. Following the Romanche and isère (= flat) or crossing the Vercors (= medium mountains). Given the next two stage will probably be medium mountains, I guess it will be flattish.
Stage 14: Valence - Mende; medium mountains with the finish on the altiport (but from which side?) (****)
Stage 15: Millau -
Carcassonne (***); medium mountains with Pic de Nore?
restday
Stage 16: Carcassonne -
Bagnères-de-Luchon (***); medium mountains (Portet d'Aspet, Menté, Portillon?)
Stage 17: ... - Loudenvielle (***); high mountains
Stage 18:
Lourdes -
Luz Ardiden; high mountains + mtf (**)
Stage 19:
Pau -
Formigal (**); high mountains + hilltop finish. Some rumours about Formigal
Stage 20:
Saint-Pée-sur-Nivelle -
Espelette (**); (very hilly) itt. There are rumours about a 30km long itt between the two aforementioned villages.
It could be interesting.
Stage 21:
Compiègne - Paris (****); final flat parade, the start isn't all that important. Some vague rumours about finishing on the course of the 2024 olympics road race. It is possible that that course is implemented in the final parade stage, though.
