ssshhh....don't let ASO getting ideas....It'd be ironic for the TDF to go to Finestre after having paved Portet and La Loze.
Uh if you wanna add Montevergine it's gonna be a wee bit long
The chances of ASO doing those 6 climbs followed by an uphill finish in Briancon would be......... zero unfortunately.far better stage between the cities
Mollard, Galiber, Montvergine (west) Finestre, Sestreiers, Montvergine (east), upfill finish in Briancon
or if you didn't want to do 2 trips over the montvergine
st francios longchamps, mollard, mont cenis, finestre, sestreiers, montgvergine, uphill Briancon
