Sorry for asking for the same help as other people. Me too... at the end of an eight hour ride the fit file says corrupted. Possibly because the battery was so low
I also have a corrupt .fit file. I tried to fix it with http://garmin.kiesewetter.nl/ but it didn't work. The whole route is gone. I also tried to fix it with https://www.fitfiletools.com/#/ctf#view. Garmin didn't recognise it and Strava recognise it but he shows run from 1680km (in stead of 15km) with a sprint to Russia. Then Strava gives a crash. Is anyone here who can help?
Answered in the other thread you started. Please don't double post requests for assistance, it makes it frustrating for those of us who volunteer their time to fix .fit files to sort one out and then find it has also been sorted by someone else in another thread.
