Correct and Edit bad GPS points in an Activity

Occasionally I've had problems with my cycling GPS data, and have been getting spikes and spurious readings which result in strange route fits, and miscalculation of actual distance traveled (usually overestimated). Are there any plans to allow for manual pruning or manipulation of bad GPS data points by the user, thereby allowing Strava to "fit" the route more closely to the actual ride? Obviously, my phone is the culprit for the bad data, but it would be really useful to have the ability in Strava to either 1) remove/edit the wonky GPS points, and/or 2) to fit/nudge the route manually to existing roads on the map when the route is not properly tracked. 

I've heard that other cycling apps can do this, but I don't have any experience with these. I think it would be very helpful for those of us who want our Strava logs to reflect our actual mileage :) I realize it's probably easier said than done, and of course this would effectively kill any segment stats in the affected area. But since I use Strava mostly for mileage and mapping, and less for segments (though I do use and enjoy these), I wouldn't be as concerned about the effects on the segment calculations. 

Anyways, thanks for considering this. Keep up the good work!

    Some great tips and tricks in this thread on how to fix existing problems with GPS data! Thank you for sharing.

    It's quite an intensive project to build a GPS-editor tool for Strava. It's clear that there would be great value in investing in this project - however, it is not currently planned. Please keep adding your votes, and we're always happy to consider this project for a later time.

  • Agreed, Eric. It wouldn't be an optimal fix, and the effect on the segments could be pretty significant. One potential method would be to have a "mask"  feature akin to the Crop Ride functionality, wherein the user could select a specific customizable region to ignore (presumably one with bad GPS data). Another would be to nudge/reposition the route. Of course, as you mentioned, the edited/masked region would not be eligible for segments within and/or flanking that region. But with bad GPS waypoints, the route, mileage, and speeds are usually vastly miscalculated, so the segment data is already inaccurate and the offending segments would be useless anyway. How Strava would treat  the ignored region(s), (e.g. connect the dots using best route fit vs remove the ignored region mileage altogether) is open for question.

    This is not a life or death feature, but it would be nice to at least have the option to tweak things to keep the routes accurate, even at the cost of losing some segment functionality. This with the caveat to users that editing the route will impact segments.  My guess is that such functionality would be more useful to those users who are more concerned with route accuracy than with the competitive aspect of things.

  • I also would love this. Having just done an epic 26 hour ride I would love to cut out the straight line bits where my phone was on charge in the support van and to move my finishing point also after the battery had died again. Just being able to edit the map of the ride and draw in the actual route taken would be brilliant. ( that or find a smart phone with a decent battery!!)

  • Another pointless "me too". even though something like this obviously takes a back seat against the really vital features like posting your selfies to Twatter or FacePuke... or whatever other pointless "social meeja" crap they add next.

    Here's a particular favourite of mine, where I ran along and back on a straight-ish path leading through some woodland:

    As you can see, according to Strava, I suffered from a severe bout of St. Vitus dance along the way, which means that the timings for whenever I run that particular route are completely bolloxed now, as I can never hope to match the pace I set when apparently rattling about like the proverbial wasp in a jam-jar.

    As if the lack of editing wasn't stupid enough, there's also the complete lack of any "intelligence" [artificial or otherwise] built into the app. One time when I forgot to stop the tracking after a run, and then drove home, Strava was pleased to tell me I'd covered six miles in about ten minutes and award me several "personal bests".

    Luckily, that time, since it was at the end of a route, I was able to remove the offending section with the 'crop' tool. But who builds an app that doesn't sanity check the fact that someone can apparently run 6 miles at a constant pace of around 35mph?

  • For this to be something added, Strava would also have to eliminate those "edited" sections of the ride/run for eligibility in any nearby segments.  This could lead to a slippery slope of moving waypoints and skewing segment data.

  • Mike, you can trim off the start and end points of your ride. When you log in from the website (not the mobile app), select the ride and then click in the wrench icon. Select "Crop Ride" and it will take you to a module that lets you crop off the starting or ending points of your ride. Great for situations like you described.

  • GPS is GPS right - I need the same ability for my runs.  I have been adding little segments here and there to make up for when Strava says my run is too short, but I have no way to crop it if Strava says it is too long.  Either way it's a pain to deal with this discrepancy.  It is a pretty basic feature request if you ask me, Garmin, Training Peaks, DailyMile, and SmashRun all let you edit your runs (or rides).  I don't understand why we don't have this here.  https://strava.zendesk.com/entries/43144320-Ability-to-Edit-Distance-Time-of-an-uploaded-activity

  • Right, as I've mentioned a few times elsewhere, SmashRun, TrainingPeaks, Garmin Connect, etc. all allow you to edit your own data to correct for discrepancies...  so... why not Strava?

    • This is now 4 years old, and still there isn't a solution as in runkeeper, where you can edit an activity that was incorrectly recorded, or where the recording stopped halfway through. Went three hours on a bike today, and strava decided to have a break after 40 minutes and never come back.

  • If Runkeeper has a editor for segments why can't strava have one? I broke a record of average time commuting to work today, When I looked closer the whole segment was filled with wierd spikes and top speed over 100 km/h. Come on Strava make it happen!

  • I would like to think someone is reading this and would like to improve the site by adding a missing bit of functionality, but I don't get that feeling unfortunately; I've mentioned it in another thread and Twitter a few times without any responses yet...

  • Thanks @Elle, then can you or someone else at Strava please tell us why this would not be added?  Otherwise I may as well just manually enter distance and time for our runs/rides if that is the only way to get an accurate entry onto this site.

  • Just been for a run - I know it's 2km one way, 2km back.  Took me 20 mins.  Strava (or iPhone?) had a really bad signal (lots of spurious points away off the road) for first 1.5km - it has calculated the distance as 5km.  Hence pace of 4min/km whereas shoud be 5min/km.  I'm happy!  But a fraud!!  Please fix this so points can be edited etc!!

  • +1 for the same feature. Most other run tracking apps I've used allow me to edit the route when my phone dies part way through a run. I'm puzzled why Strava doesn't think it is a priority.

    Current workaround is GPX export, and import into Runkeeper or similar which will let you edit and re-export. Then delete your Strava item and import the new GPX file.

    (messy, but it does work)

  • Here's another lonely voice telling another sad story....Went on a ride and in the middle of the ride I stopped for a bit and paused Strava....started back up and forgot to unpause. Unpaused and Strava happily pretended that I flew in a straight line from the pause location to the unpause location. I would love the opportunity to edit the track to snap to the roads/trails that I was actually on. This feature should work similar to the google maps route editing capability. If people are worried about people gaming the system for KOMs then use the phones GPS tracking history to ensure that the user was actually at that location at the time of interest... Add it to the next dev sprints PLEASE. :)

  • I would like to see Strava add the ability to edit the overall distance of a run or bike ride, even if this editing ability causes all segment/elevation/mapping to be deleted.  Another option would be to mirror a previous run or ride that didn't have gps problems, i.e.: I ran the same route today that I've run 10 times before, let me use the previous good gps route with today's time and heart rate information.

  • Any update on this feature becoming available? I really enjoy Strava in other respects, but my GPS has failed a couple of times recently, and if other similar services have implemented it, I think I would be forced to switch to using them rather than Strava.

    Thanks,

  • Editing incorrect GPS information needs to be implemented! - does it need to be made any more clear that this is considered a necessity by the people who use your app?

    The entire point of your app is completely undermined by these glitches - before I used Strava I used to go to Google maps, draw my route and measure it - time-consuming
    and tedious but at least it was accurate and didn't decide that i'd flown like Superman across blocks to rejoin the route when it found the signal again..

    If this is 'hard' to implement employ some more programmers. If you run the same route week in week out as i'm sure most people do then why can't it compare the two and
    figure out that you probably didn't fly over a bunch of houses? - why can't it interrogate the data and 'know' that you can't just suddenly move thru blocks of buildings like a ghost?

    Before you set out on a run couldn't you tell the App what run you were doing so it could compare the GPS it got with a previously stored route so that it could query spurious
    readings that are way-off base?

  • A sad state of affairs.  My stats are also goosed.

    Can anyone from Strava confirm whether this is being worked on or whether it's still in the wilderness?

  • I recently ran a 15km trail race and my Suunto Ambit 2S recorded it as 14.97km.  As it was one of my fastest 15km's I wanted it to be recorded under my best efforts.  Long story short, Strava does not allow you to fix it as pointed out in this post.  Luckily, by making use of other free online services, I was able to correct it (https://www.strava.com/activities/768088561).

    -  Export as gpx from Movescount or Strava or whatever service you used to record it.

    -  Delete activity from Strava.

    -  Use https://tapiriik.com/ to sync activities between different services including runkeeper

    -  Select activity in Runkeeper and use the Edit function (https://runkeeper.com/user/686482512/activity/891957213?tripIdBase36=er1ql9&activityList=false&)

    -  You can't just change the distance figure so I moved my start and finish GPS points both a bit until the distance showed 15km

    - Export as gpx and upload in Strava and done.

    By the way, if you want to compare all your best estimates for various distances in a convenient way, make use of http://stravabestefforts.com/.
