My brand-new Fenix 6 Pro Solar is suggesting substantially higher HR than my Fenix 5S (and the previous Suunto I had for that sake).
I am a long distance runner do +200km/month and I am in fairly good shape. I usually do +15km workouts with 4.20-4.30 min/km pace without making a great effort. Just to put things in context.
The first two times I have worn the 6 Pro Solar it has suggested my average HR to be +185 for the full work-out. Today I went for a 10km run and slowed down my pace with 1.00 min/km just to see what happened - I felt I was almost walking, yet it suggested my average HR to be 168 for the full workout and that I even had a max HR at 199...makes no sense whatsoever.
Counting all other watches I have had, then when I have pushed my limits the most and even in extreme conditions, then the highest HR ever measured has been 194!
Any idea to how to fix this and/or address this best possible with Garmin?
