Thanks for that tip, track points were set to 3000, now set to 10000! That is indeed an obscure location to hide them.
I hadn't actually noticed the 'most' setting. I've now set it to that as I only do day rides so may as well get as much detail as possible.
My workflow for strava uploading is cumbersome to say the least, but it does work:
* Download tracks in easygps.
* Delete any unwanted tracks so that I only have the 'active log' track
* Save as new file
* Open file in text editor and make sure that it really is only the active track that is contained within.
* Upload to strava
Cumbersome, but does at least work.
