Fenix 6S Pro inaccurate cycling distance

The Fenix 6S Pro seems to consistently record distance covered inaccurately. Inaccuracy is around an extra 1km per 10km recorded - ie the watch records 40km, other cycling devices record 36km; the watch records 25km while other cycling devices record 22.5km.
Is this something that can be resolved? I appreciate recording all activities on one device. I appreciate the recovery time estimates, intensity minutes record etc etc. Recording cycling on a separate device makes all the stats and advice on my watch inaccurate. In which case, what’s the point in having the device if it is unable to record all the proposed options accurately?

Are you using only your watch GPS or additionally any external sensors to record your bike rides?

I have been using two sensors in hope of transitioning to just one.

Then it is probably an issue with sensor calibration.

Sensor calibration
try to "not to use the senson on fenix, and, the will see

Thanks #Matthias# :) How do I recalibrate the sensor?

I am often riding in groups with multiple sensors (heart rate straps, speed and cadence sensors, watches, Garmin/wahoo etc bike computers). Do you think that going to be a problem?

I do ride with many friends, that's not the problem:

erase the sensor from your fenix, and then onnect it again:
If it doesn't work
Erase it again and take de sensor battery off
the pair again

I am not sure as I don't use a speed sensor, but I think calibration settings are in your watch settings under 'Sensors'

do you mean you are using a speed sensor on the wheel hub?

There's nothing wrong with recording cycling activities on a separate device. As long as you have Physio TrueUp enabled on both devices then you should see accurate stats on your watch. I record most of my cycling activities with an Edge 530 bike computer and it works fine.

Get a speed sensor if you don't already have one. That will more accurately track distance even when GNSS signals are poor.

Set GPS to "GPS + GALILEO". This will use more battery power but should improve accuracy a little in most areas.

If you have an external heart rate monitor, then take the watch off your wrist and mount it on the bike handlebars. This should improve GPS reception slightly.
