Forerunner 945: Wrong stride length for outdoor run when paired with RD Pod

I am getting the same problem starting a few weeks ago. It was working perfect before, but it suddenly started to show less than 0.5m stride length using RD pod. When I use chest heart rate monitor to measure the stride length, it shows correct numbers.

I do not have Garmin HRM sensor, because I have already had Polar H10 for a rather long time - so I cannot compare.

From the other side - if I would be fan of conspiracy theories, I could think that there is a software restriction to work correctly for 1 year. It worked nicely in February 10 (https://connect.garmin.com/modern/activity/8271658497) less than one year after the first use of Run Dynamics Pod. I did not use it for following treadmill runs (too much slippery ice here).

Stride length measurement/calculation has not worked correctly after that.

• Measured stride length behaves erratically (esim: https://connect.garmin.com/modern/activity/8425843312) or is simply wrong
• Run Dynamics Pod no more shows in Garmin Connect website for runs when I have used it (I last see it for 10 February run mentioned above)

Some possibilities:

• I used Run Dynamics Pod together with Under Armor Hovr 3 Infinite shoe sensor (only used as foot pod) several times for treadmill runs after Feb 10. Maybe some problem caused by both them used at the same time

I told Forerunner 945 to forget it and reconnected. Let's see what it will show in next run. Maybe I should also tell to forget UA shoe sensor

I'm seeing the same. It seemed to occur after my 945 updated to 9.0. I also note that on most find I no longer get vertical ratio (%) values; and when I do it's only a few days points for the entire run.

I wonder if it has to do with the CIQ version change.

With RDP everything works, I just checked yesterday's ride

I tried to install firmware 9.56 beta and did a short test run (earlier 11.5km run was using firmware 9.00 and Run Dynamics Pos support was broken). In this short test run all seems to be OK. So perhaps the regression in version 9.00 is fixed now in latest beta version

That's great to hear. I'll await for the beta to move to final.

Same RD Pod issue over with the FR245:

I just posted this also over on the 245 chat:

My stride length has also been WAY off since the software upgrade to 9.00.  My stride length always shows 0.5 to 0.6 meters now, no matter how fast I run.  This was a fast run, so my stride length should have registered as 1.2m or so on this particular example.   I submitted a ticket weeks ago, including all my log files, and still the issue is not resolved.  So my pod is basically useless. 

Since I have no idea if they will ever fix this, I just returned my pod today.  Maybe if they ever figure this out 5 years from now, I will buy another one.

Good luck all!

Got a very similar issue on a Fenix 6 after the 21.00 firmware update

Appears to be impacting several series of devices (FR945, FR245, Fenix6, etc)
