If your distance is accurate, it certainly was!
Yes, I had to add in the 6.5 miles where the gps wasn't on. Strange since you can see where the watch was recording time and elevation in the first track for that portion but not speed or distance.
Maybe a download problem? I've occasionally had an issue where all of the time but only some of the distance shows up on AP, but downloading again fixes it.
Not a download problem. I could see after skiing for 6 miles that the distance had not changed despite the fact that the timer was running. I think I've since figured it out. You can't just hit start again, you have to go into the activity menu and select resume. Strange.
