@nassosc getting accurate wrist data for distance on a treadmill is likely not possible. Only a footpod will be accurate. Treadmills are notoriously inaccurate as well so be careful how you make comparisons.
-
@Brad_Olwin I understand that but my surprise is that I had excellent results before. With the same watch and the spartan. Not 20-25% difference.
-
Had a talk to my coach today and he confrimed that the treadmills are calibrated.
Did a 15k run and the S9 logged 9.89k!Will try to downgrade the firmware
-
@nassosc Need to have @Dimitrios-Kanellopoulos check on this. Should not have been worse. Can you confirm that GPS is off?
-
@Brad_Olwin yes gps is off.
-
Do some running with GPS outside and it will calibrate accelerometer. Because every update wipes calibrated data.

Right.
The problem is, that you need some technical background to explain the behavior of the watch…
And even then there is a lot of guessing about the functions happening in the background.
Why not add an indicator in the watch information about if calibration für walking or running has been completed? Just two flags should not be too difficult to add.Or a warning when starting a run w/o GPS, that the accelerometer has not yet been calibrated.
Or at least a hint in the manual.
-
@SlaSh unfortunatly I have done a run with the GPS, actually it was the run before the 3 horrible treadmill runs. Will do another one since my options are limited. Thank you.
-
There was nothing touched regarding the accelerometer. Try to reflash the FW or reset
-
Did a FW reset and a GPS run and accelerometer seems to be calibrated. Just to set the record straight…

I’m curious, am I reading this right that if you update the watch, the calibration data for indoor distance, etc is wiped, and you must again do the run outside to recalibrate before it’s accurate indoors again?

@oeagleo I have updated the watch several times before in the past and callibration was not needed. Not sure it was a bad update (if that is possible) or it just needed calibrating.
-
@oeagleo watch update is clearing cached data as accelerometer calibration profile and other, so you need to do activity with GPS to get it calibrated again. This is nothing new Farmin watched act the same after upgrade.
-
@nassosc and how treadmill distance and etc looks like now?
-
@slash treadmill distance is correct now.
-
@nassosc what solved it ?
-
not sure, did a watch reset and a gps run. after that the treadmill distance was again ok
-
I totally agree with you…
I am 45 years old…y I was sustaining 219 BPM for more than 20 min at the beginning of my work out…
Incredible… or I am a SuperHuman

@Marcel-Baliño its all the good training! well i get the same error and after about 8-10min it drops to normal levels. As far as I know it is problem with the sensor software that some encounter and it will most probably be fixed in the next update.

@Marcel-Baliño ohrm or belt?
