How do I export as a TCX file from Garmin to upload into Strava? My 2 accounts stopped syncing yesterday and I think I've fix it now but need to manually export from Garmin Connect (web) and import into Strava the missing runs.
The Strava help files say I need a TCX, FIT or GPX file to import but I can only export CSV from Garmin. Am I missing something?
Thanks.
