I don't know if I'm the only person that this has happened to, but lately my Nano has been losing my workouts. For example, I went running tonight, and did a good 4-miler, paused and ended the workout and when I pulled my Nano out of the armband, could see my time and distance. I turned it off, went inside, and plugged it into my Mac. iTunes said "Sending workout data", but there was no prompt as usual to go to the Nike Plus site. I checked the iTunes Nike+ settings, and it didn't have my last workout listed, it had the one before. I checked the Nike+ site, and it doesn't have my new workout. I even ejected the iPod and checked it, and it's missing my workout too! This is the third time this has happened, and it's not consecutive. It seems like a random occurrence, but I haven't done anything differently each time it's happened, so I can't explain it. Has this happened to anyone else, and is there a way to get my workout data back? Thanks!
