I'm trying now, for sometime to take a .gpx file created from caltopo.com to Garmin connect so I can add it as an activity to my Forerunner 230. I'm pacing someone this weekend in a race and having this would be extremely helpful. The file format is .gpx. When I go to the Activities section of Garmin connect and load the file in through the Import function, it says not all activities were imported. Turns out none of them are importing.
I've been looking into the existing files there and they're .FIT. Do I need to convert the file to .FIT? If so, how is this done?
