Since one week (starting June 23rd), when running, my intensity minutes in Connect are off. Sometimes they seem ok, but on other runs they didn't. I did 5 runs this week, and 2 seem OK, The other 3 aren't. Those 3 runs I ran at low speed, and thus low heartrate. basically zone 1 and only very limited zone 2.
On these 3 runs Garmin shows 1 minute of moderate, and all the other minutes as vigorous. So that would mean Z2 and Z3, but like I said, I only ran Z1. In the connect app my activity minutes are now doubled. I use my 970 together with an HRM600 since the beginning of June, and can't remember changing anything in the set up this week.
In the Connect app I've configured the setting for activity minutes as:
- Moderate Zone 2
- Vigorous Zone 3
My zones in the connect app are:
- Z1 from 122 to 134
- Z2 from 135 to 147
- Z3 from 148 to 160
On the 3 runs where the minutes are incorrect I didn't exeed a HR of 135 BPM.
A possible reason that I can think of is that (and it may sounds weird) is that on the 2 runs that are ok, I ran with a buddy who uses my old 965 and old HRM Pro+. The Pro+ was still present in my sensorlist on my 970. Mayby my 970 sees the HRM Pro+ and all is OK, and when I run alone it doesn't. On all runs Connect shows my HRM600 as the source for HR. But that doesn't explain why it only started this week, because I use the 970 and 600 before this week aswell.
Any suggestions, or others experience the same issue? See screenshots.
