Categories are fairly subjective and are assigned by the tour or race
director, and sometimes a given climb can be a different category based
on where it falls on the course. A climb might be a cat 3 if it's early
in the stage, but a cat 2 if it's the finishing climb. Here's a good
primer and there are several others on the web:

My understanding is that a Category 1 climb is a 3,000 foot climb that
rises continuously without interruption. I do not know the the
standards for Category 4, 3 or 2. There is no specific standard for HC.
It is just a climb that is considered far beyond a Category 1 in
difficulty and length.

Subject: [OBRA Chat] Question about Hill Gradient and Categories
Can anyone tell me how to calculate average gradient for a climb? For
example what is the average grade of a 1 mile climb that gains 400 ft of
elevation? (or does it even work like that)Also, what is the "rule" to
determine a category 1-5 or HC climb. Thanks.
