Just a quick FYI: the UCI does not rate climbs. Climb rankings are always at the discretion of the particular race promoter and what they put into their "race bible". In fact, the same climb can have different rankings dependent upon when/where in the stage/race it occurs.
MapyMyRide does at least have a consistent formula for ranking climbs, but it has nothing to do with UCI or Pro-Tour races.
