Cleecyclingmamil - there is not a single data record contained in your file. Not a lot I can do to assist.
How many completed and uploaded activities are still on your device? If it's any more than a months worth then consider archiving them off to a folder on your computer. It could be a case that there wasn't enough storage room left to write the data to the .fit file at the end of your activity.
I will look at that. Thanks for having a look. It shows on the device as a 56 mile ride. Don't know what's gone wrong. Device has plenty of storage left as well
