Nike + SportWatch GPS

Just in time for your leisurely jog across the river to watch Monday's big finish, these newly released only-available-at-five-stores-nationally timepieces are powered by TomTom, let you mark laps by tapping the screen, show your mapped route, track your distance/time/pace/heart rate/calories burned, and even remind you that it's time to run, presumably every time you accidentally get off the T at 1a in Andrews Square.
