I just finished running a virtual race (Possum's Revenge 69 mi) and I'm supposed to provide a link to prove that I ran it. Of course, when I try to upload my run I get an invalid file error and it won't sync. I've tried syncing with my phone, syncing with my computer, downloading the file and uploading it to Garmin Connect, no luck. I even tried a few .fit file repair websites but couldn't figure them out. I've linked the file below if anyone can help.
