Frank's Haleakalā Climb
Yes, this is certainly a hors categorie ("beyond category") climb. That is, it's off the scale, beyond the categorization of difficulty determined by the international governing body of cycling (UCI). Semantically, it of course actually means highest category.
Though very long, at 5% grade, it at least wasn't steep. -F.
