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!

  • Since this request has been around for a long time, I guess it'll never be fixed, but I *really* hope that by keep bumping this thread it will.

    It's pretty annoying that if there is an issue with the GPS on a run, the only way to change it is to download / manually edit / reupload; even more so that you have to do all of this on a computer. This activity for instance - I'm pretty sure I didn't run across a river. And now if I don't edit it, my PRs will all get messed up.

    The reason I signed up for Strava was the ability to pick up my phone and run, and then have a look at the data post-run. I really don't want to have to worry about lots of manual steps to show what I actually did; if there was a way to slightly change the route through Strava, that would be excellent.

  • 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?

  • Stobsai, exact same issue! I really smashed all my speed records on that one.

  • Adding my +1 with a couple of examples

     

    Max speeds 95mph and 128mph respectively. Impressive for a mountain bike! 

    The first one meant I missed a few key segments that would have been PB times (ironic that perhaps one of the reasons they haven't implemented this is to stop cheaters setting PBs but instead its stopped me setting one?). The second added one about 10 miles to my ride. 

    We all know GPS errors happen and it isn't a problem that Strava picks these up as so does any other app but not being able to do anything about it is ridiculous.

  • It seems obvious that the only way Strava will listen is if everyone cancelled their subscription.  Money talks!

  • It sounds like the issue is well know by now, but I experienced a particularly problematic run today.  I went just under 10 km with about 900 m of climbing but strava said I went 57.4 km with over 3600 m of climbing.  It also said my fastest km was 5 sec.  I realize GPS receivers can have trouble in the mountains, but as others have said, it would certainly be good if there were a way to delete the problematic points easily; just as it is already easy to cut off the end of an activity if you forget to push the stop button before getting in a car.  All I know to do is to delete today's run entirely.  I know - first world problems...

  • 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've used this Snap Raceshape tool for GPS drift correction / editing issues.  Twice it's polished the data and found the segment that GPS missed.

  • Same problem, Garmin gps lost contact with Sats and took off across country before getting back on the route after a few miles. Need to crop middle and manually link the true tracks.

  • I had my phone is airplane mode towards the end of a metric century.  The phone keep auto pausing while I was rolling and created straight that dont follow the road messing with my mileage.  I got to the end of what should have been 65+ miles, but it only read 60.1.  I would be nice to get the lines to overlay the actual road to get accurate mileage.

  • Same problem, GPS probably couldn't get a good signal resulting in an added 3km to my run and skewing the average. Is there really no fix to this yet?

  • The most painful of these errors is when Strava adds the rest time at the top of a climbing segment to the climb time. This happens often when you turn back down after resting. There is a solution for this: Split the ride into two rides. You can include the rest time in the second ride. True, you have two smaller rides instead of a long one. But it is worth it if you had a hard to get PR on that climb. It will show up as PR then.

  • +1 Unreal that this is a 3 year old thread. I work in tech and pretty sure this is what you call validation for a feature.

    I guess that the most frustrating thing is that this was already accomplished on Race Shape. Strava has already integrated the compare feature from Race Shape.  Strava could even add some controls so you couldn't fix a point that would change a segment start/finish.

  • I have found the solution. 

    Bulk export all your data. Then open an account with Runkeeper and bulk import the data. Runkeeper allows you to correct the map data manually by adding and dragging waypoints on the map. Once done import the corrected run into Strava and compare with older version.

  • Just use a different app for logging. Strava is useless if you actually want to know where you ran and how long it took you. Then you can sync to strava for the social stuff which they don't really do better than most other apps, but more people use strava so it is the go to. Endomondo is my go to and I use https://tapiriik.com/ to automatically sync.

  • A little shocked to see that this is still ongoing since 2014. In Runtastic you can edit your route with a few clicks, why is it so complicated and disappointing at Strava?

  • I've about had it with Strava now. I've had a series of runs lately with these spikes and additions. Strava, just do what all the other apps do and allow your users to clean up their routes when the GPS has a hissie fit!

    Thanks Runkeeper, for letting me do what I should be able to do in Strava.

  • I would suggest forfeiting any leader board stats from edited segments.  you won't get any leaderboard credit anyway for gps fails, but you'll be able to keep track of your personal fitness goals.

    and FYI, the  Map My Ride app has the ability to edit routes.  Sorry to mention a competitor, but honestly, if they can afford it, Strava should be able to also.

  • I am shocked and disappointed that this isn't possible, especially after seeing many years of comments and requests! My phone battery tanked during my ride today, so I lost a good 5 miles or recording. Bummer to not be able to correct it. I agree that if you alter your route it should become ineligible for the leader boards (or challenges).

  • That's why I stopped using Strava and now use Map My Ride and Ride with GPS.  They just don't get it that I could care less about taking pretty pictures along the route but I do care about an accurate record.  For those of you still posting to this question, maybe you should go elsewhere.  If enough do that, then maybe, somehow, they'll get the hint.
