Is it me, or has anyone else found it difficult to edit a run after uploading it to Garmin Connect? I thought it would be just a matter of erasing some of the run I don't want, after stupidly forgetting to stop my watch at the end of a race

I thought it would be just a matter of erasing the bit of the red line of the route I didn't need. It seems however that I have to either alter the page of CODE!!!!! Or buy some other software such as Basecamp or Mapsource to be able to edit my run.

I just wondered if anyone else had managed to edit a run after the event without being a computer whizz, which I'm not. The page of code scares me to death!
