Repaired using Fit File Repair Tool.
Unzip the file then import into Garmin Connect using the [import data page]
The Forerunner 25 seems…
The 245 is not normally an issue, but I would start with removing all files in the \GARMIN\ACTIVTY folder regardless of what it says is available, especially if you have chronic corrupt file issues.
Best I can do is split this into 2 rides, leaving out the gap between 1:20:45 and 3:55:38. Sorry.
From the event log:

Thanks.
I guess it's an issue with the actual device. Appreciate your help.
Hi Seilogramp, I too received the following message when trying to recover my .fit file from my garmin Edge 820.
If i can attach my .fit file could you please take a look at it to see if it is recoverable?
Much appreciated thanks,

Could you please fix my Totals.fit, kisewtter.nl won't accept it with the Line 151558, position 9 error code. I would like to add data from my previous bike computer (Sigma 800), it's a total of 326:47 (hours:mins) and 6285.9 km. Ty in advice!
