Running Distance Off by a huge distance

I recently participated in a 10K event and noticed that my watch's distance tracking for running was off by a lot. It was measuring more than actual distance. My watch had completed 3.5 miles when I reached the actual 5k mark (off by 0.39 miles). Having a 0.1mi difference could have been understood due to my starting position and events tracking via corners etc but 0.39 mi was a lot. It didn't end there. The gap kept on increasing and i finished at 7 miles for a 10k distance. That's off by 0.8 miles in total. My friend who was running right next to me with an Apple watch had 6.3 miles on his watch.

I didn't have GPS switched on but I have run before with the same watch with GPS turned watch and it was way more accurate earlier. Anyone with same issue? Any solutions?

    I have the same problem with my vivoactive3. I ran with my forerunner 235 on a track with distances, and it proved very accurate. when I run with vivoactive3, there is a difference of 20m every 300m. I would also like to know if there is any problem with the configuration or is it any update that should be done.

    "I didn't have GPS switched on"

    It's only ever going to be an estimate without the GPS unfortunately - all it can do is multiply your cadence by a stride length.

    I run many times with running partners who have non Vivoactive watches. I am off (shorted) a half mile for every 6 miles. Over a years running and that is some major missing mileage on my mileage goal

    Since update 3.90, I have the same problem, see the example below:

    run activity on Vivomove 3S w/o GPS connected: 33:16, 7,25 km, 4:35 min/km, 170 steps/min, 1.28 meter/step

    same run on iPhone SE with Adidas Running : 30:49, 5,01 km, 6:09 min/km, 169 steps/min, 1.0 meter/step

     

    The positive thing is the step rates are the same.

    But there is 28% too much on step length, that's the problem, it's HUGE !!!

    As you can see the problem is with the step length, but I have set the step length for running in Garmin Connect to 0.93 meter and the Vivomove 3S uses 1.28m, why this difference ?
