The hill I am climbing and descending is about 2 km at about an average 6% grade, as high as 12% at times. Total ascent about 150 m (500 ft) or so?
I am pushing 60 now and from what I have calculated, 150 bpm is a decent cap for my HR, though I have not done an FTP test.
What I would really like would be just to be able to pedal a bit faster when I can only manage 6-8 km/hr, as well as maybe get a little faster on the descent.
