I know very little about how LTHR changes with improved fitness. I've been riding seriously for about 18months so think I've probably missed some of my more significant changes. If you're doing a climb like Diablo or another of the local hills, do you try to keep your HR at or just below your predetermined LT, or do you look for a certain amount of anaerobic feedback to let you know when you're at your limit? i.e. if your LTHR goes up, you can presumably push harder without going anaerobic and climb faster.
I can generally calibrate LTHR with how my legs feel - when I start to get at or slightly above it in constant efforts, my legs start to ache.
As you train, your LTHR reaches a higher percentage of your maximum rate. You can put out more power without going anaerobic and you will burn a higher percentage of fat at a given heart rate.
As for climbing, it depends on what my goals are. If I'm trying to go as fast as I can, that's one thing, but if you are training, you want to spend the bulk of your time either above LHTR or below, and not a lot of time near it.
