The other takeaway from my ride is going (relatively) slow is good for long distances. Even an easy 19-20 MPH produced HR at 125 when pulling and 115 when pulled.
I think you're doing great. If it helps to monitor the ticking of the ticker for training purposes or to make sure you don't overdo it, then you should. I used to use a HRM 20+ years ago. I was passing a pretty young lady during a group ride when the alarm went off to let me know I was above my "Max" HR which I had set according to some formula or other. I don't use a HRM anymore; I will be satisfied if my heart explodes while hiking, biking, or banging.

Hey, I'm 62! If I die, at least I won't have to pay any more alimony.
