The finish at Pozo Alcón (stage 7) is expected to include a loop with two linked climbs: Vadillo Castril and Tiscar. My guess is that both are no more than cat2 climbs, followed by a final 6-7 km going up at 3-4%. Anyway it looks like an interesting finish.
Stage 8 will finish at Almadén (flat).
Stage 9 will depart from Talavera de la Reina and will be 226 km long, but there's no mention of any climb before La Covatilla. We'll have to wait for additional details.

ITT will be in Cantabria, probably in Torrelavega. There are no details on route and distance, but according to ciclo2.com it should be between 30 and 40 km.
