Jazzbri said:Il y a actuellement des travaux ( et ce pour quelques années encore ) absolument partout dans Briançon. La ville change de visage, et se modernise . Je ne vois pas donc pas Briançon accueillir le tour en 2019.
Google translate produces this:
"There is currently work (and for a few more years) absolutely everywhere in Briançon. The city is changing its face, and is modernizing. I do not see Briançon welcome the tour in 2019."
If that's true then passage through Briançon could be problematic. If the Tignes stage is true then i don't see anything before Iseran but the upper Maurienne hills like Aussons etc. The Val Thorens stage will probably include Roselend and not Madeleine. There will be some secondary climbs in between like Montvalezan or Montagny i guess. I wonder if it will decided to use the D96 at the bottom.

Rethel, Thionville etc. are apparently out and will be replaced by your usual set of Reims, Épernay and Nancy (or to be more exact - Métropole du Grand Nancy). Also, the Pau TT is for Vuelta.
As of now, this Tour doesn't shape to be too great. Tignes and Val Thorens are interesting choices and potential Valloire with Galibier is also quite unususall but the rest seems to be relatively tame. Wonder, what's with that Prat d'Albis rumour as i don't think there's any space for a finish. I guess it'll end on your usuall Peguere-Foix combo. But then in 2008 they did Portel from Rimont. I also wonder about Crouzette south and Portel - overally similar to Peguere but less regular.
