      @tuxella the recalibration happens a the time with gps based workouts.

      If you run in a tunnel that is straight then the GNSS distance from gpx recalculation (or check it on qs) will be ok and right. If the watch reports more it indeed does not use so we’ll the fused speed or you look many times at your watch.

        The tunnel more or less follows the yellow line bellow, which I think is pretty straight.

        See also the openstreetmap routing: f6e5664b-dad6-4de2-b732-c87d7f383794-image.png

        https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=48.85891%2C2.33983%3B48.86052%2C2.33101#map=17/48.86011/2.33463

        I don’t think I looked at my watch more than once or twice under the tunnel (which is ~700m long). The cadence and speed reported on points while I was under the tunnel look ok to me in QS.

        Can I do anything to help the watch (using fusedtrack or not) for my next run?

          @tuxella I suspect the watch may be double counting the tunnel distance in this case - the first time from accelerometer and the second time from GPS when it reacquures the GPS signal. The easiest way is to download the FIT file and inspect the distance over time in it, and see if there are any sharp jumps in the distance. In my experience Ambit3 had exactly the same issue, which I observed several times.

            @sky-runner we have fixed this issue quite some fw before.

              This “double counting” theory could explain the results I get.

              I analysed the data in the Suunto fit file from the 30/03/2021 :

              The first time in the tunnel (difference between the first and the last point without coordinates):

              • Distance: 0.87 km
              • Time: 4:15
              • Speed: 12.28 km/h

              On the way back (in the same tunnel):

              • Distance: 0.88 km
              • Time: 4:19
              • Speed 12.23 km/h

              If I add these distances to the distance calculated from GPS coordinates of each point:

              7.74 + 0.87 + 0.88 = 9.49km
              

              Where the total distance in the fit file (and reported in Suunto App, QS, Runalyze, Strava…) is 9.58 km

                @tuxella can you make the links of qs public ? You can easily see if it’s that bug which was fixed

                Currently I cannot open those links

                        @tuxella I’ll take a better look when I am on my pc.

                        I do see the issue.

                            I have the same problem with the s9b after the last FW update. The tunnel length is counted twice. I tested with Glonass as well as Galileo.

                                          @dimitrios-kanellopoulos I had this issue twice: on the 30/03 and on the 09/03.

                                          On the 09/03 I wasn’t using the “new firmware” (which was released on the 30/03 AFAIK)

                                            @tuxella I did open a bug report in any case… Something is wrong here.

                                            Strangely while I tested this I didn’t get this issue. so lets let the watch guys figure this out.
