Sorry, probably didn’t explain this to well, I’ve recorded a load of rides using my phone and wanted to crop rides to extract segments for some climbs/laps/time trial courses where ive set a pb. Just got a new garmin so wanted to use these as individual courses to race against using the training partner. I would prefer to open the segment ‘course’ during the ride as I go rather than have the whole ride mapped out.
Solution was fairly easy – sorted it by manually editing the gpx xml. I used tcx converter to identify the start and end points using the preview, thanks for the recomendation. I think you could edit the gpx from within tcx converter but found it a bit buggy – often crashed when exporting after i removed points. I was using the mac version so might try the windows version instead
Riding them again to get the baseline was just too simple a solution!
