Calibrate Nike+

Options
EEK! I tried using Nike+ on my iPod Nano just to see how it compared to my Garmin. I expected it to be off with calories burned, but it was RIDICULOUSLY off with distance traveled.

If you use Nike+, please be sure to calibrate it properly.

Yesterday I ran 17.57km (10.92mi) and burned 1499 calories per my Garmin HRM. Nike+ said I went 13.27mi (21.36km) and burned 1788 calories. That's a pretty hefty difference IMO.
