Libertine Seguros said:They've never been east of the Col de Jau though. And barely west of Larrau.
You could do a proper Pyrenean stage in the very East, maybe with an Andorra finish, since there's Coll de Creu, Col de Jau, Coll de la Llosa, Puymorens/Port d'Envalira, Dent, Port de Pailhères, Pradel, Chioula and Bonascre there. Then with the second Pyrenean stage you could go westwards using things like Lers, Peguères, Crouzette, Portech, Col de la Core and then have Portet d'Aspet (probably harder to avoid this one!) and finish at Ski Station Mourtis, or do Menté + then go to somewhere like Superbagnères. Then from Pau, Lourdes, Tarbes or somewhere like that you could skip horse**** like the Tourmalet and lead-in with something easy like Porteigt, then go Bouesou/Labays, Issarbe, Larrau. That's as long as we're believing the lie that the French-Basque roads can't take the Tour. Bagargui has handled it before.
I also thought of a Andorra finish, but i've never been to keen on them. It would be something different from Peyresourde, Aspin and Tourmalet, but I really don't rate the climbs around Andorra are that interesting. Too long and not very steep.
The two other alternatives you suggest are much more exciting. I like the idea of a stage finish at Mourtis after Aspet with a few climbs before that.
And especially I would like to see a stage in the border areas to Spain. Using climbs like Arnosteguy, Bagargui, Larrau. Is there some climb in this area which could be used as a stage finish?
