Based on the rumours so far, this race design could go either way:
Worst case:
"Single climb" stages to Etna, Aramogna, Matajur, San Domenico
Not much more than Stelvio/Torri di Fraele and Finestre/Colle de Basset on those stages.
Nevegal as the stage finish for the Dolomite stage
Best case:
San Domenico as the only stage with only one big climb
Double Etna climb, Citelli before finish at Sapienz
More climbs before Stelvio and Finestre on those stages
Proper Dolomite stage with use of several of climbs like Duran, Giau, Staulanza, Fedaia, etc.
