@Massimo-Cerè sounds excessive to me too, although it depends on both the status of the satellites around (e.g. how high are there on the horizon) and the height of those buildings. But you also said you checked the data of other people running, so it seems this affected you more than others.

[Massimo Cerè]

@isazi Exactly, my other friends with very cheap GPS have not had this problem

[isazi]

@Massimo-Cerè so an error of 1.5k over 42.195k is 3.5%. And your track does not even look that bad to me, I expected much worse. Was it the first race with this watch? Did you tested it on other courses with known distance?

[Massimo Cerè]

@isazi I tried it even on shorter distances, but it always measures a little more, on the half marathon, wrong by 600 meters more

@Massimo-Cerè Had the same Problem with my Spartan Sport WHR at the Berlin Marathon this year. My watch showed 42,9 km and at Berlin half this spring 21,6 km. In both races I started from the front and so could run nearly the blue respectively green line.
Some difference is ok, but in my opinion thats to much.

You do not possibly use a Stryd, paired as a FootPod? Because that happened to me (the “too long” distances) as long as I used the Stryd as a FootPod and not ‘only’ as a PowerPod. Since I changed the Pid-functionality I am no longer that fast , but the distances seem to be more reliable.

@Shrek3k did you also play with stryd calibration?

[Shrek3k]

@isazi I did - unintendedly - it worsened the results (approx 2 months ago with older Suunto FW); since I changed the Pod-mode and avoided calibration it became better in a way.
Better: the distances in SA/MC stay GPS-driven, and I have all data in Stryd without duplication in Stryd;
not so good: it is less comfortable and I have no GPS-track in Stryd,
but as long as Suunto is not able to use/handle/fuse the Stryd data in an acceptable manner (without losses of data like leg stiffness etc) this seems to be the only way (for me) to use both apps/gadgets.

@Shrek3k interesting, thanks for sharing your experience. I’m still waiting for mine, and will test it in January.

[DirkM]

@Shrek3k I used the watch without any pod.

[Shrek3k]

@DirkM ok, than - of course - that can’t be the reason at all …
