not that lucky are you

happy sporting

Strange, how does the recorded track look like?

Concerning the elevation change, this could well be within the error margin.

Does not really help in your case, I had excellent results with the 945 on a track, even better than the 935 did, which was also very good.

Here is the file. thanks for your help.

I changed the distance to the right result. If used the laptime all 5 rounds (2 km), two or three times a little bit  later.

you could make use of the GPS beta firmware here ... gps-chipset-beta-2-42-now-available

Nothing special to see in your fit file.

GPS recalculated with the logged coordinates gives the same result.

I installed the update 2-42 and will test tomorrow.

I would recommend not to use Galileo yet. It was doing a fine job with the old chip (Fenix 5, 5+, Forerunner 935), but ist crap right now on the FR945. I do a lot of runs in the woods near Frankfurt Airport, a place were Galileo coverage should be fine and the runs don't like to astonishing...

Using GPS+Glonass leads to better results and cleaner tracks.

Running on a track in rounds is a tough think for GPS watches, DCRainmaker ones did an article why. 

Almost 6% difference in the distance is too much, we don't have to talk about this. Thats bigger than my error running on treadmills without calibration.

The elevation change is in between 214 and 221 meters above sea level. This means, the watch had a spread of only 7m in 6 hours running in circles. This is a good result. It calculates up to 76m rise and 63m fall, but you have to take into account changes in internal temperature and changes in barometric pressure in this 6 hours. I wouldn't be mad about this.

By the way:
Was tun die euch Niedersachsen ins Wasser, das ihr 6h auf ner 400m Bahn lauft? Da wird man doch Gaga von. ;-)

I did a triple Marathon on Saturday here in Germany.

GPS + Glonass, intelligent recording.

Official distance: 3x 42,4km = 127,2km

FR945:  42,72 + 43,44 + 42,68 = 128,84km

I´m pretty satisfied with the watch.

And that´s with running beneath tree shade, between two bodies of water (Dove Elbe and Eichbaum See), 48 times around. I know every stone there now. Gave them names, too ;)

I think I've gotten better results with the beta gps firmware with GPS+Galileo than GPS+Glonass before beta.

And it's a pity that the new GPS Watch is not up to the old one's :(
