so i sent back the Fenix and it got replaced.
Today i runned again with both Runkeeper on iPhone and the Garmin.
Same story: 8.49km on the iphone while 7.66km on the Garmin.
Same timing.
I read around on the web, and it seems to be a common issue, and that the Garmin should be more accurate, while I thought that the iphone would be.
Any other experience?
at this page i found more info:
In System / Settings / Data Recording try ‘Every Second’. Smart Recording is not smart at all. It helps.
Thanks.
Then no solution? Just accept that it's not an issue with Garmin, rather a problem with the Fenix series?
I suggested you check whether you’re recording every second or Smart recording. Also try GPS / GLONASS
The Garmin Support centre has articles on improving GPS. I can’t link the article for some reason.
Done it already.
However from all these conversations it seems a Fenix issue rather than a Garmin issue?
Possibly Fenix issue or setting. I used that article I referred to to check my setup and am currently on beta 26.81.
I run a regular track with markers at 250 metres. Allowing for dodging people I’m generally 240 - 260 metres at markers.
I do 2 things to check mine after run. I export a gpx file from Connect and import it to Suunto app. Guaranteed it will be 200 -400 metres on Suunto import on Run and for walk 100 metres per 5 kms.
About once a month I track on Suunto IPhone app and also import the gpx into Suunto and they’re close (+- 50 m).
i read a forum post a while back (can’t find it). Basically, the Garmin saved file has ‘smoothing’ apples by Garmin for the various metrics but once file is exported and imported to other app that smoothing is not applied.
