Apple Watch 4 running distance VS exported gpx file

Thanks for you reply.

Even calibrating the AW4, is anyone else experiencing the same issue?

How does AW calculate the distance when running? based on the GPS or based on the pedometer? or a mix of both?

I use the Watch to track the workout and then HealthFit to export the data to Strava and to Dropbox (GPX file).

Strava and the Watch show the same distance. The point is when I visualize the GPX file that is when I see less distance (I can upload the file to Strava and see the difference between what has been automatically imported and the GPX file).

The GPX file is based on the GPS location each second and this is what drives me crazy, why if the Watch uses the GPS to track the workout the result is different?

Thanks

If so, I don't understand the difference between the GPX file and the actual distance in Apple Workouts. Both should be the GPS data.

Any other ideas?

Hi there,

Anyone else experiencing the same issue with the distance?

Thanks

You mean to export the file? if so, HealthFit.

I've contacted Apple Support, hopefully they will call me today.

I will write something here once I got the call.

Apple's response is... "calibrate your AW"... don't know what to say.

I will use Endomondo APP for my next running workout. Let's see the distance difference between the APP and the GPX file.

Perhaps Apple Workouts is correcting or fixing the GPS data somehow so the distance is actually based on the GPS data + some adjusts from the APP.

Let's see how it goes.
