I have a dinosaur Garmin Forerunner 301 that still works perfectly. I have noticed the feature of trimming activity is not available for activities uploaded from it.
Could anyone shed some light on this?
The document says "GPX or TCX activity files do not support Activity Trimming. This applies to manually uploaded GPX or TCX activity files and files uploaded by older Garmin devices that only record activities in those file formats." What format does Garmin Forerunner 301use for uploading? The uploading is done by Garmin Express, so I thought it was supposed to have more to do with the Garmin Express version than the device.
