Heart Rate Sensor issues?
Looking at HR charts from my last 3 runs I noticed a sharp drop in HR at various points. I thought it might be elevation or pace related but it doesn’t look like it. I wear my Fenix 7X SS on my left wrist and have a metal band that keeps it reasonably snug to the skin. I do have a chest strap that I’m going to try to wear next time to see if I get similar results. Has anyone seen anything like this before? While I’d like to think my body is getting adjusted to the new routine (I’m 3 weeks into training for a half-marathon), I’m not sure.
