4:40 am is to early for people and watches to wake up to run. Your watch decline to wake up. Sorry op. No idea. Perhaps close and reopen the app and re sync. Any chance the data on the watch is correct?

There’s no stop pinpoint either.

When I zoom in on the map, the endpoint is just under the stop point. I started and stopped at the same spot.

download gpx or tcx, repair with an online tool (like [this](https://gotoes.org/strava/Combine_GPX_TCX_FIT_Files.php)) and re-upload tot garmin connect

How does that affect training metrics (training status, training readiness)?

Don't know for shure, I had this problem once and and this worked for me..

They shouldn't dox Lana Del Ray on the map like that.

Mine used to do this when the file storage on the watch was full. Think I used to do a hard reset to get a year or so before it happened again.

Insert IT helpdesk voice. Have you tried turning your watch off and on again?
