Garmin Edge 500 non-auto-resume / filling in the gaps in a GPS file

Folks, On a recent ride, I discovered that my otherwise trusty Edge 500 had lost 15km and about half an hour off the trip. After much head-scratching and googling it seems that this was due to an issue with auto-pause/resume feature in the Garmin Edge 500.

Folks,

On a recent ride, I discovered that my otherwise trusty Edge 500 had lost 15km and about half an hour off the trip. After much head-scratching and googling it seems that this was due to an issue with auto-pause/resume feature in the Garmin Edge 500.

Apparently if the battery is low on the speed/cadence sensor, or if the magnet on the wheel is out of alignment, it can cause auto-resume not to work. A Garmin support person posted somewhere that when there is a cadence/speed sensor present, the Edge will only auto-resume when the sensor detects wheel revolutions, and will happily ignore GPS data that clearly indicates you are on the move. So at several points on my trip, the Edge auto-paused, but didn't resume until much later. Next time out I replaced the battery, realigned the magnet and things seem fine.

So my question is now that I have a GPS log with significant chunks missing, does anyone know of a tool that will relatively easily fill in the gaps in the log. Ideally I'd like to be able to say - "see this gap here - fill it in by assuming I traveled at a steady pace along this road from X to Y".

Worst case I could export to a GPX file and edit it manually, but that sounds like very hard work.

Any thoughts?
