"we don't support the file type you tried to import" - 12/30/2023 run

Hi mcgryboski, the Forerunner 25 and 35 are prone to corrupt file issues. These sometimes can be fixed using an online tool, such as FIT File Tools, using the section remover without any adjustments. Then upload the repaired file to the Garmin Connect import data page - https://connect.garmin.com/modern/import-data

If that doesn't work, you can attach it to this thread. We can take a look to see if it is repairable.

• Zip the file, then in a reply post Insert >> Image/video/file >> click Upload >> browse for file >> OK.
• Or upload the fit file to a reputable file sharing service, such as OneDrive, Google Drive, Dropbox, make the file public, then paste a link to the file in your post.
• Or if you'd rather your activity remained private, you can send me a private message.

Thank you!
