Raven, you describe a situation that is gradual, and that makes total sense. But with Suzie, it was like one day her average heart rate was in the 120s to 130s, then the next day it sunk below 110 and never went back up again.

And we challenge ourselves on the longer rides. We change the routes, go longer distances, do more hills, and so on.

I've experienced the lower heart rate on the same hills too. It is very gratifying to see. But for myself, I push myself harder and the heart rate goes back up.

Raven and Zen, what are the average heart rates for all of your rides?
