HRM Run w/955 FW 15.19 - No Run Dynamics

The last time I wore a HRM strap was before 15.19 and it always worked fine. Running Dynamics w/out the HRM strap also work fine. However, this morning the 955 only recorded HR and respiration rate from the HRM strap. Everything else was blank. I did structured intervals configured on the the fly (on watch) as I walked out the door which is also normal. I'll try the strap again tomorrow (easy run). 

I just  looked on the phone GC app, and it shows I got about 20s before it all went to nothing. 

  • Well, I ran w/the HR strap again this morning. Everything worked as expected.Running Dynamics were recorded.

    I didn't configure a workout, just ran. I'll try it again on Friday while configuring a workout to see if I can reproduce the problem I had last time.

  • Pay attention that the band has its own up and down, if you put it upside down the running dynamics don't work. The Garmin lettering does not have to be inside out!
