Auto save activity on shutdown.

My activity didn’t seem to auto save when my watch battery died. Can I retrieve it anywhere? I know it recorded at least 92km of my first 100km ultra.

Try manually importing the activity file using a Mac or Windows computer - How Do I Manually Upload an Activity I Recorded to Garmin Connect? | Garmin Customer Support

If that doesn't work and/or you're getting an error message, try repairing the file using FIT File Viewer.

If you’re still having trouble uploading the repaired file, attach it to this thread so we can see if it’s fixable.

Zip the file, then in your reply go to Insert >> Image/video/file >> Upload >> browse for the file >> OK.
Or, you can upload the FIT file to a trusted file-sharing service like OneDrive, Google Drive, or Dropbox, set it to public, and share the link in your post.
