My max observed heart rate is periodically going up. Good/bad/neither?
Starting cycling last summer. Within a month or two I hit some new observed max hit rates and didn't think much of it.
This spring, when I push myself 100% for some 30 second time window, etc, I'll max my heart rate. Only it seems to be getting higher from month to month.
Last summer a 100% effort landed me at 180. Today I hit some highs when I did some sprinting during our 25 mile daily ride and my max observed is now 187.
Now, I realize that raising your max heart rate has little to do with what we're trying to accomplish in training. Training (to me) is mostly about how much power I can put out at a sustainable pace, how long I can maintain that pace, etc.
But as a side note, is this increasing max heart rate typical? 187 seems rather high and I'm wondering if it'll keep going up! I'm 36. I'm riding frequently enough that I would definitely consider myself to be in good shape (albeit with more pounds to lose).
