I recently had my Edge 530 run out of battery. I charged it up and recorded an indoor ride only to discover that the Edge thought it was a previous date and time and recorded the activity as such.
After some researching and many sync attempts, it turns out the clock reset was as easy as setting the device to an activity profile that uses GPS and leaving it in the window for the satellites to sync. My customized indoor activity profile disables GPS to preserve battery (a lot of good that did? not sure how it ran out of juice, but that's another story).
Now that that's fixed, there's still that ride data that's in the past, which affects the Training Status and some other analyses that I've been enjoying about the 530. I've tried uploading the fit file that Zwift sent to Strava, but that doesn't seem to register in the reports such as Training Status, Training Effect, or VO2 Max. How to doctor the ride data from the Garmin to take place on the correct day so the analyses see it?
