Hello all, Did a swim activity yesterday with my Fenix 3 and Swim-HRM and problems seem to arise when it had trouble uploading the heart rate data post-swim. Original file was corrupt enough that I couldn't upload to Connect, Strava or even upload it here. I resolved enough using Fit File Tools "corrupt time fixer" to upload to Garmin Connect with all data, but that "fixed" file still is identified as corrupt by Strava. Exporting the "original" or GPX file from Connect allows Strava upload, but without HR data. Exporting TCX file from Connect is identified as corrupt by Strava. For clarity, all HR data shows on Garmin Connect. Tried the Garmin Online Tool with no luck and attempted FitFileRepair tool, but it appears the age of my laptop is probably holding me back. Any help in "de-corrupting" or allowing all data to transfer to Strava would be much appreciated. Neither the original fit file or Connect exported GPX or TCX file would upload here. The attached file is the "Export Original" file from Connect. Thanks for your time. Darin Wink 4233269605.zip
