Another: How long did it take to calibrate the foot pod? Considered getting one. Also, how far/close are the pod and treadmill distances, if you looked?
Since I just did this recently I'll chime in with my results. You calibrate from an 800m run on the track. So it takes 3-4min + the effort of going to the track. Mine has been surprisingly close to the distance on the treadmill, usually +/- .02mi per mile. Good enough for me. I suspect the treadmill distance is the more accurate/consistent of the two.
