Exclude Power Data from the Power Curve for an Activity

I have some rides with bad power data (i did not calibrate my powermeter before the ride). 
I would like to exclude those rides from the power curves, without deleting em (i like to keep track of all my rides on strava).
Perhaps a a checkbox could be added to the Activity's properties (the same place where i can check "Private") ?

  • Thanks for the excellent suggestion.

    As a workaround in the short-term, if you export a file from Strava as GPX, the power data will be removed and you can re-upload the file. Without power data, it won't disrupt the Power Curve feature.

  • The ability to exclude power data from certain activities would be very useful. Especially for run data that has power as is corrupting the power curve and makes it unusable.

  • Totally agree. I would love the ability to hide or delete power data. Some people probably feel the same way about HR. I started getting bad power data from a Stages Pwr Meter as the battery was dying. I want to keep all of the other ride data (and comments), but delete the power data as it's seriously screwing up the power curve, F&F, etc. Please add this feature.

    I tried the 'download GPX', 'delete,' and 'reload GPX' file, but the bad power data still remained...

  • Hello,

    Any news on this feature request? Workaround suggested is not acceptable, as I don't want to loose kudo's & comments by exporting & importing gpx files for strava rides with eroneous power or HR data. 

    Would be great if the deletion could be done with a click (or2) per ride

    Regards

  • For those of us with foot pods exporting running power we MUST have the ability to make the curve just include cycling or (as the case may be) running.  The curve is now useless for me.

  • I just tried the export - re-import for a tacx turbo ride and the GPX included the power data. :-(

  • This feature would be nice my power curve has been off all season b/c of bad power data from one ride.

    I managed to find a workaround. If you can get ahold of a .FIT file of the session (I got mine from Garmin connect) you can use this program to strip the power data (or HR, cadence, etc).

  • i first tried stripping power data in Training Peaks and although it works in that app, even after recalculating it within TP, it is still in the file, and so if you export afterwards, Strava still sees it. 

    I then tried https://www.fitfiletools.com/#/stripper#view and you can drop a file onto the page and decide what you want to strip out - I chose power, then downloaded file and manually imported to Strava.      (There  is a link on that page to export directly into Strava but not tried that method as didn't wan to type in password etc.)

  • You need to remove the power meter data items directly from the rides data file. One way to do this is to rename those data items in the file so strava does not recognise it. It seems to just ignore it then when you upload it. You can easily do this manually.

    So to do this for a ride that is already on Strava:

    (1) from strava export the ".gpx" file for that ride to your pc.

    (2) open the gpx file on your pc with notepad

    (3) replace all occurrences of the text "power>" to "powerdeleted>"

    (4) save the file  - use a different file name so you dont ever lose the original

    (5) delete the ride from strava

    (6) upload the saved file in step (4)

     The ride will now appear without power meter readings. Strava (today!) ignores data marked with the tag <powerdeleted> . Obviously comments kudos pictures etc will be deleted but you will get your power curve back to where it should be.

  • Thanks Dan/Stephen. 

    good hack for removing dodgy power readings. 

    I used "peak stripper"  https://www.fitfiletools.com/#/peak#view

  • To echo something: You can do this very easily in Training Peaks, so I don't see why it hasn't been added for Strava.

  • The following just worked for me:

    1. In Garmin Connect edit the activity to remove average power, maximum power, and max average power

    2. Export the edited activity into a file

    3. Import the file manually into Strava

    4. Without these 3 aggregate data points, Strava interpreted the file as having no power data and reverted to its estimated power

    Thus my F&F stats were restored and all is right with this part of the universe.

  • Tried the above without success so I've still got an annoying anomaly. Strava really needs an internal way to do this.  I only went premium to see my power curve but now its corrupted so I may go back to the free version.

  • Ditto this. This would be a simple checkbox on the activity detail page.

  • Thanks Ceall, works a treat.  Strava, please support this feature!  1 bad set of data messed up my power curve.

  • Please add this feature Strava! The power curve and fitness/freshness features are rendered useless without the ability to exclude bad power data.

  • Please can someone from Strava respond to this thread and add this feature?

    I now apparently have an FTP of 900+ because of a dodgy reading yesterday...   I've managed to tell Garmin to ignore the power data from that ride - can Strava please also allow this feature?

    Thanks

  • My stages got water ingress and i have an ftp of 1020 watts for one ride! it was a trip to the alps so don't want to delete it.  Looks impressive but not ideal on the power curve.. Please add this feature strava!

  • My harsh take: If Strava can't incorporate this, then the very nice Fitness and Freshness-feature is actually useless.

    My Stages did not like the heavy rain shower I encountered on my last long ride, and gave readings of 2400 watts and beyond, pushing my FTP up to 656 watts. It kind of defeats the purpose of Fitness and Freshness together with the social functions, if I need to export the ride and delete it from Strava, take the file to a third party and strip it for power data, and upload that file to Strava - then my ride, along with the pictures, kudos and comments are lost. My Garmin device loads my ride on auto, so that whole process must be anticipated in advance, after coming in from a long and wet ride. I can tell you this much; corrupt data files was the last thing on my mind...

  • Come on Strave, sort this out! A simple tick box. That’s all was ask for. Pretty please?

  • So, just to check if I got the thing clear, this issue is around since 2015 and still no fix from Strava? Seriously?

  • Alessio - yes, correct

    You’d think even more so with the new “fitness” metric on the app they’d fix this.

    I have one ride from 5 September which has +40% power error. But I don’t really want to delete the whole activity, lose the grand fondo, lose the km, lose the CTL. 🤷‍♂️🤷‍♂️

  • I'm crossing my fingers hoping this get addressed. I had an issue from years back that was addressed this year. I had a big race filled with comments and kudos that I'd rather not delete, but i'd also like to not have data with 2000+ watts messing my power curves. Please fix Strava!
