Since the garmin oregon, dakota, gpsmap62 are able to use hartrate and cadanse sensor it is not possible te edit a track in mapsource/ basecamp.
When saving the hrm/ cadanse data is lost.
When you upload from the device directly a part of the day before was also listed, when the reset was not used at the start of a trip.

It would be nice to cut a track in useful parts.
original track: http://connect.garmin.com/activity/49451213
edited track: http://connect.garmin.com/activity/49450859
Or are there other options.
