Courses: Import file and keep the original elevation data

When you import a .gpx file for a course, GC "corrects" the elevation profile. There should be an option to maintain the original elevation data (if it exists), similar to how it is handled with activities. GC's elevation correction is really bad in steep areas, especially side hill trails where minor discrepancies between GPS coordinates and their elevation model appear as a significant noise in the elevation profile. So, I'd like to maintain the elevation data in my .gpx file.

Hi Danny,

I fully agree with your statement. Unfortunately, Garmin seems to be quite reluctant to acknowledge it: https://forums.garmin.com/forum/into-sports/garmin-connect/troubleshooting/1439163-handling-of-elevation-data-within-garmin-connect-platform

Thanks RobertMUC .

I've learned that I can stick .GPX files directly into the Garmin/NewFiles directory and it appears that the elevation is good. So for now I'm just not going to use Garmin Connect for courses.

Thanks Danny!

I tried this and my 70km trail run course copied directly to NewFiles shifted from Garmin Connect reported 300m elev gain to more realistic 1100m (still differs around 100m from "raw" gpx file), and it even shows the climbs somewhat correctly when previewing the course on watch (FR945).

It still has some issues and it is a little weird that it includes a lot of flat ground before the actual climb as part of the climb, when the climb is short and steep, but that I can live with....

And now as we are getting that PacePro this comes even more important! If they want us to have proper courses they should not f.. up the elevation in the courses.

I fixed GPX elevations with GPS Visualiser and then small convert with GPSies that Garmin connect accept it as activity (as I have bad experiences doing this with some import, they usually just are bad). Then with the activity I can disable elevation corrections and see proper data, but if I select "Save as Course", the course will have elevations "corrected" and I've not found a way to disable that. Sucks.

Oh my good thanks! I was getting mad with differences about 1000 m elevation from original tracks of wikiloc (hiking) imported to GC. It is awful that Garmin do not let the users disable that corrections.
Meanwhile, I'll try to copy the .gpx to the storage unit of my fenix through the computer. Thanks Danny.

Ya this is seriously unacceptable for use with PacePro. Any course that goes over a bridge is f'd up beyond recognition with no way to correct in Garmin Connect

I have the same problem. every time i import a course in Connect it boost the elevetion up about 1000 mt D+. it's annoying

this only happens to my if i import a course via garmin connect. the elevation data is ridiculous. if i import the same course via the komoot connect iq app, the original elevation data that also feeds into climbpro is correct. that's why i am using this workaround. something with gamins algorithm is broken?! i am also seeing these spikes.

i also started a discussion - including pictures here:
