.fit file will not upload but works on Garmin connect
I was wonder if anyone can help me out. I have a .fit file which works perfectly on Garmin Connect but will not upload to strava. The ride consists of two fit files and spans a 90 hours for 564 miles. The one short file of 87 mile uploaded and i deleted it off strava to try to get the full ride on. I have tried to combine the files and change the date strava on the analyst says done and the line is only 1/2 way and it will not let me save the ride. Every time i try to upload the file i get the duplicate file error.
Any help would be appreciated.
