I did a Half Ironman on Saturday and found out the file is corrupt and won't upload to Garmin Connect. I tried various tools to no avail, but I'm not really sure what I'm doing. I used the multisport function on my Forerunner 745 (swim, bike, run and transitions) and didn't have any issues during the race. My friend did the race with me and she is having the same issue. Same watch. The only glitch we noticed which may or may not be relevant, was that I was wearing a heart rate monitor and she wasn't, but occasionally her watch said her heart rate monitor was connected.
Thanks for your help!
