One of tried variations: all runway in one segment, separated by trk - /trk tags. The bars between runways as the original multisegment version.
The result visible in this track:

@Vgyuri/traces/885283

Sorry. If I can solve this basic problem, all other data are in my databook.

Do You have a track with correctly separated subtracks, e.g with runvays?

How can i divide a track for subtrack? I have 42 airfield runway in one GPX file. (From OziExplorer 84 trackpoints) I tried use the - , - and - pairs, but after upload all subtracks are coupled with long lines.

I must upload 42 object with 42 separated upload?

I delete the airfield tag. But my track contains 42 tracksegment, 2 coordinates in each. This are separated runways on several places of Hungary. The result not separates subtracks and there are long lines between runways. Isn't there possibility to upload more subtracks in one file?
