I'm using this at the moment:
Pretty neat way to back up your trainings and also to import them to AP (in case you're an AP donor which I think you're).
How I do it:
After flowsync has done its job, I open v800 downloader, tick the "unsaved" trainings and download them as tcx. Then in AP, add training
-> upload files
and double click the just downloaded file.
Btw, it might be possible that in the future AP can download trainings straight from the watch (like Garmin and Suunto). At least when I contacted Ken few months back, he said he will look into that. Though I guess he has many things to look into :/
