Can anyone explain how to join multiple .fit files together? my edge 510 crashed a couple times and stopped communicating with my vector pedals (power meter) and speed/cadence sensor during a ride yesterday. i managed to pause and save the ride into 3 separate files but cannot figure out how to successfully join them. I have tried the CombineActivities.jar java app as posted by another user but only receive an error when trying to process the files (i used Garmin Training Center to export as .tcx first before running the java app).
Please help the computer illiterate!
