SG, I made a mistake. My waking HR on Sat 28th May 1988 was actually 26 bpm!
It had been 28 bpm two days earlier.
Combination of severe interval training, severe diet and being in a very cold room first thing in the morning.
A few years later I was discovered to have some problem with blood calcium levels. It's calcium which has some bearing on how electric signals are transmitted around the body. So I guess I was healthy and unhealthy.
HR doesn't mean much, and as mud...fun mentioned, it's your own property as such.
When I had a resting HR of 37 bpm (normal) there was an international runner of my acquaintance whose own resting rate was 45 bpm.
Then we started to run.
At 7 min mile pace, I was on 165 bpm. He was on 130 bpm.
At full race pace (5:30 miling) I was around 185 bpm, while he was on low 150's bpm.
He like me, could operate with a HR of mid 180's.
A 1500m best of 3:42 and a five mile best of 23:39 said it all.
Needless to say, I didn't get to see much of that.
