I asked the same question about the Omloop Het Nieuwsblad previously.
Basically, I'm not sure why I haven't seen any references to the TA climbs being categorized. I haven't seen any profiles that say Cat 1, Cat 2 etc...
Does anyone know if the categorizations exists? Can you point me to ithem? Or, can anyone take a shot at comparing the climbs in these races to the Cat 1's, Cat 2's, Cat 3's etc... in the Grand Tours?
