I lost my iPod in Spain, but thought I had all my runs saved on my computer.
Important notice: your runs are only stored on your iPod until you upload them to nike.com
There are 20 kms that only I know about. You will never see them. Until, I guess, til you look at the rock that is my body!
On the plus-side, it might be good to know that the white flat nike+ thingie that you plug into the iPod survives a good warm/hot wash cycle.
