How to Calibrate the Nike+iPod Sport Kit

Posted by Filed Under: Gear & Apparel, MP3 Players, Speed & Distance Trackers

ma365lla_125.jpgOut of the box, the Sport Kit is only 90 percent accurate. You can expect (according to Nike and Apple) your sensor to be 98 percent accurate once calibrated, so it is definitely worth the minor extra effort it takes to calibrate. Here’s how:

  1. Measure out a route to use for calibration.
  2. Find a route that is a minimum of 400 meters in distance. If you have access to a high school or other public track, this is a great place to calibrate since the track is exactly 400 meters around (on the inside lane). If you have no access to a track, you can map out a route at gmap pedometer.

The following 8 steps have accompanying screen shots at the bottom of this article.

  1. On your iPod menu select “Nike+iPod.”
  2. Then select “Settings” on the workout menu.
  3. Next select “Calibrate” from the sensor menu.
  4. On the next calibration screen push the center button to continue.
  5. Select either “Walk” or “Run” depending on what you want to calibrate.
  6. If you have previously calibrated either your run or walk, your iPod will show the date of your last calibration.
  7. Choose either a “Custom” distance or the default “400 meters.”
  8. If you chose the custom distance select your mileage using the iPod dial.

You will be told to begin your workout and you will receive spoken feedback when your calibration distance is completed. Repeat this process if you also want to calibrate your walking or running pace.

Calibration does not need to be repeated unless there is a significant change in your running speed. For a list of frequently asked technical question relating to your Sport Kit, please visit Apple’s Web site.

    A really useful post! I think using a known fixed distance to measure against is a really good idea.

    Thanks for sharing.

    Thanks for the post! I have almost decided to get one of these for my nano – which I use almost every run already.

    Question, do you know if it’s pretty easy to put into another brand of shoe? Nike’s have always been to narrow for my foot, so I’m hoping to put the sensor in an old pair of Saucony’s by cutting a little hole under the arch support. What do you think?

    TREADMILL!!!!! Repeat all above on a treadmill for exact calibration

    Two responses:
    1 – Dont calibrate on a treadmill. According to NIke+ specialists it does not calibrate well on treadmills (seems treadmills are not 100% accurate with distances)

    2 – To use the Nike+ on non-Nike shoes check out this post how to attach the sensor to the show wihtout slicing up the shoe –

    I had the Nike +plus for about 3 years loved it until this summer isnt accurate anymore at all not even close. I ran 2.0 exactly it said i ran .47 not even close! Tried to recalibrate it will not calibrate anymore. Does that mean i need to go buy another one?

    hi i wonder if you can help, i’m using the nike+ kit with a pair of nike + trainers and the damn thing wont seem to calirate, i’ve tried going straight to the calibration section and running further than the minimum 400 m and yet when i end it says i havent ran far enough. then i heard you can calibrate it by doing your normal work out then selecting end work out and holding in the centre button it should give you the option of using the workout for the calibration, however it only gives me the option of deleting it. any advice would be gratefully appreciated, i’m getting so annoyed with the thing. thankyou

    I was told at Fleet Feet to take it to a track and calibrate it that way. That’s what I did and it seems to work fine. I love my Nike+. I own a pair of Saucony shoes and bought the tune belt for it. It works great. I only wish I could find a belt clip holder for it, all there seems to be are armband holders.
