Both the Cat1 climbs seem a little soft to me* , but 3900m climbing total isn't to be sniffed at!
*(is there an official criteria these days? Whatever, 'snot important)
There's no set criteria. Length of climb, steepness and position in the race. A Cat 3 or 4 in the first few days probably isn't categorised in week three, and a Cat 2 at the start of the stage is more likely to be a Cat 1 if you finish on it.
