I've been pretty good about keeping my Forerunner 35 activities clean but I did get one recently that has been corrupted. I experienced a similar instance several months ago, this activity syncs up to Garmin Connect successfully but when uploaded to Strava it complains about invalid date time stamps. It's not an especially long activity but I think the number of other FIT files on the device probably contributed to this. seilogramp or anyone else, would you be able to repair this one for me?
