You can tcx to quickroute (just change the value in the dropdown). Maybe you mean routegadget?
Sure you can always download the gpx file from Attackpoint if you need it.
gpx to attackpoint gives 1000s of kilometres.
tcx to attackpoint is fine
both gpx and tcx into quickroute give a straight line. Something must be broken.
Huh that is a bit odd alright.
You could look in the files but that seems like a lot of effort. As I said if you need the files you can download the gpx from AP after you upload it,
