Nike + ipod?

Does anyone else use this? I've had mine about a year now and every once in a while the calibration is completely OFF...I run a mile and it tells me i ran .55 mile? When I tried last time to contact Apple, it was not very helpful. There is not a simple "reset" button to reset the calibration... any other ideas to get me back on the right track/mile?! Thanks
