This will work, but the sessions don't look right 2025-05-17-09-18-46-fixed.fit

I assume this was a sprint distance triathlon? Could you let me know what it says on your Fenix 7 for each of the sessions, distance and time?

Try running it through FIT File Viewer—it works in the browser and can often fix corrupted files. I tested your file, and it imported successfully into Garmin Connect.

I'm not 100% sure what this was supposed to be, but this is what I got.
