I asked the same question about Tirreno Adriatico and Omloop previously.
Basically, when I look at the Giro website I think all the climbs are still showing a "blue" color for their GPMs. I'm not sure why I haven't seen any references to the actual categorization of the climbs. I haven't seen any profiles that say Cat 1, Cat 2 etc...
Does anyone know if the categorizations exist? Can you point me to them? I read on cyclingnews.com that the Giro program is out, but it seems like the website is not updated.
