The answer is no and yes. Assuming by "pounding" you mean walking,
then it's hard to expect much on flats alone unless you are going on
very long walks at a brisk pace skiwalking with poles, adding in an
occasional 15 to 60 second pickup (run). Likewise, taking a hill at a
pace that you can't maintain isn't much help for anything. The simple
answer is that endurance comes from a combination of long, slow
distance (LSD) over a variety of terrain, preferably not flat, and a
variety of (fewer) faster sessions specifically aimed at raising your
lactate (or anaerobic) threshhold. It should be done with a variety of
activities that your body and schedule allow, such as walk, runs,
rollerskiing (including classical double poling if possible), as
well as stuff in the gym, backpacks, rowing, biking, etc. I have to go,
so will let others fill in the blanks.

P.S. If you meant rollerskiing up this hill, then either you're going
too hard or your technique needs work to allow you to go at a more
controlled pace. If the latter, beating yourself to death doesn't
really do much good.
