Nike+

I have been thinking about getting this too- instead of guesstimating how far I have gone and at what pace... thanks for the input~

You just need to get the Nike Sensor, which is about $30. You don't need the shoes. There are several ways to "attach" it to other shoes. I put mine in an old thin sock and threaded it under my laces. The only problem I had was getting it to work at first. But, now that it's working I love it. It tells you how far you've run, how fast you run, calories burned, and you can run to your own music. Then you can download your runs to the Nike Plus website and keep track of everything.

It only works with certain Apple products though. I think iPhone, iTouch, and iPod Nano. Check to make sure it works with what you have. I would definitely recommend it.

I enjoy mine and use it especially when I'm getting ready for a 5K since you can do distance workouts too. You don't need the shoes but if you don't have Nike + shoes you'll need a little pouch or holder for the sensor. You can google it but I bought mine on eBay for less than $5 and I've seen them on overstock.com too. To use it you'll need to purchase the sensor which alone is $19 or thereabouts. If you have an older ipod you'll need to get the sensor and adapter ($29 I think--this plugs into the ipod and "talks" to the sensor). Newer ipods have the adapter deal built in and you just need to go into settings (I think) to turn it on. I just received an email that Nike has a new app for Nike+ that uses GPS--its $1.99. I haven't really had the chance to check it out but it looks neat.

I downloaded the $1.99 app and it seems to work but I don't have the sensor version to compare it to. I wonder about the calories burned though, it seems kind of low. Then again I do run very slowly.

i also downloaded the app for my i phone i love it i did have the sensor with the shoe before when i had my ipod and i have to say i thought it was great either way, but it's even better i don't have to spend money on a sensor or a shoe to use this application

Ditto this exactly!! I just got an iphone and have only run once with the app versus the senor w/Nano. I wear my HRM too to compare calories, and the sensor/Nano seemed a little more accurate, but I hadn't updated my weight in the HRM so I need to try again and see!

For anyone with an iPhone you can also get the Nike+ GPS app that records your route and all other functions that the sensor provides.
