First impression: works fine! So iPod delivers me an approximation of the instant km-pace as well as the total distance ran. It needs calibration, however, since I’m not running with Nikes. I suspect my 5K exercise today went at slower than the 4.04/km speed iPod told me. It felt all too easy to run somewhere between 3.35 and 3.55 km-pace according to iPod. On the other hand, when I tried to run really fast, I couldn’t go faster than 3.08/km… we’ll see.
