This would be the estimated power then. What is shown in the mentioned top stats will be selected automatically based on mostly undisclosed criteria in the activity.

Fenix 6X does not have running power yet Strava replaces SPM w/ Avg Power that displays nothing but zero.  Please change this back. As a subscriber I want metrics on my Activity Summary that have data to go with it.  This makes NO sense.  Give me SPM w/data, not Avg Power w/ a zero.  I shouldn't have to scroll down to see it.  Change it back!

Who says this issue is solved?  Sorry Jan,  this just changed 2 days ago and it is not showing an estimated value.  It is showing zero.  Why would a paying member want useless data displayed on their Activity summary??  SPM has data and was displayed up until 2 days ago.  Put it back the way it was.  It only makes sense!

Power has suddenly started appearing on my runs but always shows zero, and my average heart rate has disappeared from my news feed stats despite being there when I view analysis. Yet heart rate is showing for indoor cardio workouts. I've seen on another thread that the HR issue is now resolved but not for me. I've looked back over the last six weeks and all my average HR values have disappeared from my feed, even though they were visible at the time of those runs. Something is definitely amiss as I've not changed any of my data permissions.

Yes, amiss is correct.  Would be nice to hear from a Strava moderator as to what's going on.  I made no changes either and now have useless data occupying activity summary space.  Correct this Strava.

Hi everyone, thank you for flagging this. Our team has confirmed that this is an issue and are currently investigating. Once more updates are available, this thread will be updated. We appreciate your patience as we look into this!

Thank you Marya

And please allow us to customize which stats to display on summary page, not the first six random numbers of many like we have now.

Thanks Marya 

There's a related feature request open for voting:

Look forward to an update on this. I don’t need a constant reminder that my Fenix 6x is 2 years old and doesn’t track power by seeing 0w for all future runs! HR has always been a reliable metric and one of the most important to highlight.

Hi everyone, our team’s informed us that this should now be resolved. If the issue is persisting, please let us know. Thank you!

That’s over two years old so I doubt voting on it will change anything now!?

It’s just broken here (uk based user) - no power shown - I noticed this first today when editing the bike I used for ride to a heavier bike (previously I would see the ride refreshed with a higher wattage shown to reflect the extra effort expended riding the heavier bike) - how come this can’t be sorted or rolled back to how it was?- the internet seems pretty full of disgruntled Strava users regarding this …

Well… *not* voting certainly won't help to make it happen. Here's how it works.
