I am getting reports that riders who are pulling down the gpx files off my plotaroute links for rides I have created are getting errors trying to load into Garmin, or they fail to load and show as a ride at all, or indeed trying to open them in Garmin or if they do load it gets to 100% load up and then has to reloads.
I've tried to investiagte this - so far I have found this;
I see from Komoot website if I load a GPX file in Komoot - See atatched link it says there are two files. - ODD, (TCX is fine).
If I select the one showing as tour2 it brings up the route but with lots of straight connections in it - see link
I get the same issues for all gpx files I load into Komoot from Plotaroute links
However if I load the same GPX file from Plotaroute to say ridewithgps and then export it again as a gpx from ridewithgps and load it into Komott it's fine.
Why is Plotaroute creating a corrupt file?
I've put the two screenshots in Dropbox as I cant see how to add them here
See this link

Are they possibly selecting GPX Route instead of GPX Track when downloading the route? The GPX Route format only includes coordinates for each of the directions, as this format is normally used with devices that work out their own routes between waypoints, hence why you might see straight lines between them. The GPX Track format includes coordinates for every point on the route, so specifies a detailed track of the route.

Test Plotaroute Track only download. Select waypoints NONE. Than Import into Komoot.

Garmin. @ oliver les. https://www.plotaroute.com/userprofile/261276
Corrupt gpx ? Seems to open normaly in both Garmin Mapsource and Basecamp.
By the way, which format is selected by the Garmin gps users ?
Select.
- tcx or fit course file with navigation instructions. Best choice for Garmin Edge (bike) range.
- gpx (trk) track. Without navigation instructions, the track to be followed visually.
- gpx (trk) track inclusive instructions in waypoints. A "tcx clone" by gpx.
Locus app navigates perfectly with this, but not supported by Garmin :-((
- gpx route.
Final routing gps result depends on the installed routable maps and routing profile.
Anyway the Plotaroute route export is not optimal either for the following reasons.
- Route points at (instruction) positions so right at road crossings should be avoided.
As such can cause annoying track glitches and so incorrect navigation instructions.
- There is also mostly a limitation of (200) route points on GPS devices.
Total of routewaypoints at instruction locations soon exceeds this maximum.
- In fact, only the planning points, where you click to create a path, should be routepoints.
Even then, no guarantee that the gps routing result matches what Plotaroute web generates.
The Plotaroute map material and routing profile of the mobile gps hardly ever do exactly match.
I no longer have a garmin device but I made an attempt to produce a route from the Plotaroute track.
By distance waypoint tickmarks used as route(rte) points, and limiting the number to max 200.
But I did not check if some distance tickmarks happen to fall on road intersections. If yes, remove.
An 100% perfect reproduction fidelity by a (rte) route file is never guaranteed !
Due to the fairly large routepoints number the reproduction should be reasonable ok.
To be tested by someone with the hardware who wants to do so and report.
Download both gpx (rte)route and (trk)track. This dropbox link = temporary !

I also have a colleague who is also having GPX issues: I download a GPX as track, no waypoints and send it to him. Komoot will not open file (I don't know further details, yet). Workaround is to open it in bikehike.co.uk and save as GPX then feed it to Komoot.

@ Mark.
This is the tested PLOTAROUTE route link.
https://www.plotaroute.com/route/1500723
Download as track and than had a succesfull upload into Komoot for a test.
(I do not actively use the Komoot app by the way)
To discuss...add the Plotaroute route link ?

Can you email us an example file Mark? It seems to work OK for us when we try a file with no waypoints. I can't explain why Komoot thinks there are two tours in the file, which it seems to do if there are any waypoints. As you'll appreciate it's diffcult for us to diagnose why another app might be rejecting a file or handling it in an odd way, you'd really need to contact them, but we can have a look and see if we can spot anything obvious.

Admin,
OK, I've sent him one of mine and 2 from "the tested PLOTAROUTE route link. https://www.plotaroute.com/route/1500723", one with no waypoints, the other with POIs selected. I'll get back here when he's replied.
I will email you regrding some other, related issues.Mark

OK, false alarm on the simple "open a GPX" front. All files I sent him loaded fine in to Komoot.
However, ref "the tested PLOTAROUTE route link. https://www.plotaroute.com/route/1500723", one with no waypoints, the other with POIs selected", he said:
Both files load into Komoot OK straight from my phone. The file called PR_Test_POIs loads into Komoot and gives me a choice of 2 tours to import. The first option looks like a proper route, the second option appears as a few straight lines between points. If I load the second option, I then have a further choice to either import the route as it is, i.e. straight lines, or to match the route to known ways, neither of which is of much use.
Not a lot extra info, just confirmation.

Hi, with regard to "Are they possibly selecting GPX Route instead of GPX Track" - No I am using Track
Here is an example of a plotaroute file that fails in Komoot showing the two tours instead of one, interesting a gpx export fails in WeatherBagel as well.
https://www.plotaroute.com/route/1036575?units=km
Tested with Waypoints and Track Selected for download
As far as I can tell all my rotues in plotaroute will fail and I am worried more of the people using my routes will have device issues.
