Hello,
I have walked a lot today, my watch reports the following:
21135 steps and a total distance of 16.7 kilometers.
My Google Fit app on my smartphone reports : 13.09 kilometers and 20.587 steps.
Distance/Steps ratio seems quite high, do you have the impression of the Garmin watches overestimating steps or distance? I have already set up stride lengh at 0.791m (I'm 1.77m / 68kg).
