I completed an Ironman and tracked it with my watch through the multisport function. I can see the activity on my watch and shows time, pace, map, etc. However, the activities did not sync with the Garmin connect. I looked to see if I could manually upload them but there is no file in the activity folder for the day of the race.
Could this be because the file is too large? Is there any way to get the info i see on the watch uploaded? Is the file corrupt? (I noticed that the elevation tracker states i was at 0 the entire time)
