Hill Training

Doesn't matter.  Ride 'em all.  You can do repeats up the one mile altering how you ride them (i.e., do 5, 1 easy, 2 :40 seated/:20 standing, 3 at a low cadence (larger gear), etc....)  and you can ride the 5-7 miler steady with surges or just steady.  It will all help

ETA - in Henderson you have no shortage of hills! 

It really depends what type of workout you're looking for as each of these different hill types can be used for different purposes. In my mind I would use (A) for anaerobic endurance or power workout where I'd be doing more brief, higher intensity intervals with recovery in between as you spin down. For (B) and (C) I view those types of hills as better suited to training muscular endurance by riding in saddle at a decent cadence for longer periods of time.

Just how I'd view these choices as a self-coached MOP AG athlete who has read Triathlete's Training Bible a few too many times. 

I do both, but focus on the shorter intervals because that's what my races are like. My races are usually loops with hills in them, not one long hill, though we have those races too. And sometimes I just ride uphill because the view is beautiful on the top of a mountain. But for training, it's the shorter interval hill workouts.

Thanks gentlemen and Lady.  I was kind of thinking that every day is hill training for me,  but I wasn't sure if I was supposed to be doing something specific.  I think I will do the mile hill as an interval once a month and do the infamous "Ride More".  I have been slacking in the bke and swim and concentrating on the run.  However I decided (sort of) to do a century in Oct and I am already signed up for a Mary in Dec.  So I am trying to get back in the saddle.

Okay I am convinced and I will apply the same thinking to my run.  Just run and maybe do the 1 mile hill interval now and again.

18-22%  OMG....I don't think Al Gore invented that steep a grade...LOL.
