Nike+ Sensor vs Treadmill Data

SmashleeWpg

Has anyone else out there tried running on a treadmill while using their Nike+ and sensor? I've done this a few times, and noticed that my sensor usually gives me a faster pace, and more distance covered than the treadmill... for instance, if I run a 10:30 minute mile per the treadmill, my sensor says I'm running a 10 minute mile.

Which data should I trust?? Suggestions??

I have calibrated my Ipod sensor several times, so I don't think that's the issue.

I think the general consensus is that as the Nike + measures actual footfall rather than just the speed the ground is moving it's more accurate. Don't quote me on that though.

I would go with the Nike+.

I run on treadmills at the gym and each one I have to use a different speed as they are all calibrated slightly differently. There is a difference of 1km per hour between the fastest and the slowest!

Yep Nike+ should be more accurate. Just like WeightWars said - it watches your footfall where as the treadmill is just in constand motion!
