Under 8 minute pace isn't jogging. Not sure what that definition is but you were running :)
My threshold is 150HR or below is a jog. Subtract the glitch at the beginning and it's there :)
I'm still not clear what that really is. I'm generally between 168 and 175 running nearly any pace from an 8:30 jog to my 5K pace under 6:00. Might hit 190 going up a hill in a 5K race but that's the max.
I think I'm like a diesel :)
Or your watch is wrong, so weird it doesn't vary! The optical HR is sketchy for some people. Mine varies from 130 at 9:00 pace to 195 for 5k pace
Might be the issue. I was just looking at a review on my MS Band 2. "it nails GPS accuracy on par with the best GPS devices I’ve tested. Yet it fumbles horribly with heart rate accuracy, even in simple steady-state runs."
Yeah your GPS is remarkable for such a small band, but the optical HR tech just isn't quite as reliable for everyone yet.
