When uploading the ride, it is in the red sone all the way, with a new max heart rate almost 100 bpm over my correct max. With other belts I just disconnect one of the contacts between sensor and belt. Very disappointing that Garmin did not make the HRM-pro like the HRM-duo, with a dismountable sensor. Reply.

Just switched from Zwift to Trainer Road because of previous connection issues (my cadence sensor/HR would randomly drop). TR has been much better with connections but for some reason my Garmin DUAL-HRM will connect but the HR just shows up as “–”. I ordered an HRM-Pro Plus on launch day and received it on July 16. I have run with it outdoors everyday to auto-calibrate. I haven’t yet used it indoors because I’m trying to get enough varied distance, pacing, and cadence so that it will be fully calibrated. Not having a good run and not feeling strong on the run, when combined with a totally out of kilter heart rate spike, just as you depicted, was a little unsettling. Fortunately, I had my wits about me, and typed a query to the net to see if anyone else had a similar experience with the Garmin 910XT. I have an HRM-Run monitor. I have paired it successfully to my watch. And I know it is transmitting heart rate because an ANT stick I have in my computer receives it and shows heart rate. But when I run with the strap on, I get only the heart rate, any of the Running Dynamics fields I try and display all just show a blank. Restart the smartwatch to fix this problem. Press and hold down the power button for up to 5 seconds or until the watch turns off. Release the button. Again, press and hold down the power button for another 5 seconds for the watch to turn on. Go back to the Garmin Connect app and repair the watch. s38MIB.
