I’m new to garmins and I recently got a garmin vivoactive 6. When I run and walk outside, my garmin is accurate. When I run or walk on the treadmill (using the treadmill activity), the distance in the garmin is usually around .25 of a mile behind the treadmill distance. I’ve had the watch for a month now and calibrate it after each workout on the treadmill. Any tips to get the distance more accurate while doing workouts on the treadmill is appreciated.
