I am wondering if its possible to edit the strava activity recorded by strava app for any errors ( Time, distance W.R.T to cyclo computer)

The requirement for same is due to variance in results from on-board computer and strava app. Its is possible to enter the details manually however the valuable HR data is lost this way.

Any suggestions?

Yes this is possible. First up I'll be completely blunt

If you're editing your ride to make it look faster, then you're only cheating yourself.

However I know strava's app sometimes just stops. If you have a damaged ride in strava, then use the SNAP tool at http://strava-tools.raceshape.com/snap/

Feed in the activity ID number which is in the URL when you view the activity. Then you can tweak portions of your ride back to fit.

SNAP will let you download a GPX file, which can then be uploaded to Strava.com with the upload file function.

Please note, you will end up with two rides, and it will say "Atul rode with Atul" which is wrong. Once you're happy the new ride is good, delete the old ride.


If you've got a ride that was seriously truncated, and SNAP won't let you tweak it, then you have more to do.

Android Users

  1. Open Google's timeline at https://www.google.com/maps/timeline?pb then click Today and see how your ride path was - if its no good then give up here.

    1. Click the gear icon in the bottom right corner and choose "Export this day to KML" save the file called history-2017-01-28.kml

    2. We need to massage the KML fle to GPX format. First time I did this was manually with lots of copy and paste which was horrible. But since then someone's created https://kml2gpx.com/ which does a fair job.

    3. So upload the gpx file to strava, and then use the crop tool to trim it down.

    4. Since google only takes a location point once a minute, compared to strava's 0.1-10 points/sec the track is a lot chunkier. Use the SNAP tool as mentioned earlier to get it back on track.

Apple Users I have no idea - does apple have any tracking like google?

Newton / iBike / powerpod Grab the Isaac software from http://www.ibikesports.com/support/isaac-software-downloads/ and see if it can help.

Garmin / other bike computer If your dedicated hardware has munched the ride, you may be stuffed too. Check out forums - there could be a way to get some info back.

Last Resort You can create a track in Google Maps and "save as" a KML which can then be massaged into a GPX file. This is long and tedious, and your times will be completely made up. So your best plan is to

Obey rule 5, and go do the route over again.

    Thank you! I had two instances where the app just froze and shows me wrong info. I am guessing its my phone, will try your steps if I see this again – Atul Mar 5 '17 at 18:27

    @Atul try to minimise other apps, especially those that use the GPS. When I had a cheap single core phone, the app would be starved for CPU sometimes, so don't even use it when doing a strava run. Unlocking it to check the screen is okay, but taking photos would kill the recording. A higher-specked S5active works better. – Criggie Mar 5 '17 at 21:27
  • Just interested: why do these things happen? strava.com/activities/842314565 the beginning of the ride is somehow broken. What can be done to avoid it? – k102 Mar 13 '17 at 8:04
  • @k102 that looks like you started riding while the unit still had a poor GPS lock. Assuming the start green dot in Lesnoi is your start, then the Garmin kept its last known location at shutdown. But the GPS coverage was poor for the first 82 seconds and GPS lock was hard to establish. The only fix I've found is to start the recording a few minutes before you leave. I start Strava, then get my shoes and gloves on, start the gopro and then leave. Consider asking a fresh question, or using the Bicycles Chat room.
