My question - does your Nike plus online profile simply mirror the data that's on your receiver/iPod?
Here's my problem.
I originally had about ~460 miles stored in my profile and they all used to be reflected on the Nike plus receiver/iPod as well. But during a recent workout, my iPod said it couldn't detect a receiver so I took it out and plugged it back in. I then did a workout and only found afterward that all the previous data had been erased. So now it only shows the workouts that I did in the past week.
I'm worried that if I sync it with my laptop, it will overwrite all the existing data in my profile. Or will it just add to what's already there?
Hopefully this makes sense. If you have any inputs, please let me know.
By the way, I also had to recently replace my sensor - does adjusting to a new sensor replace your previous history mileage as well?
Any help would be greatly appreciated!
