So yeah, I have the Nike + Sport Kit for my iPod. Basically it works with a tiny transmitter you place in your shoe and tracks distances and times while you run. Well, I bought it back in November as I was getting back into running after my surgery...and today upon syncing it to the computer, Nike informed me I just hit 100 total miles. Not to mention I also completed a goal of running a certain amount in 4 weeks.
Isn't technology grand?
