It doesn't calculate when your running on the treadmill

[Laurel101]

The Blaze is cool however it doesn't calculate when your running on the treadmill correctly with miles done. Find myself wondering if I should press play for run or treadmill. Also the app or should let
You let your workout because this isn't not as accurate as I thought only has a delete option. They should up date well they need to update which you can probably record workouts and edit them and put it the right miles. Also well if you try to log in a run or something you can only do up to whatever miles to .9<<<. Which is annoying especially when you did more than that .

Hello @Laurel101, when ruinning on a treadmill ypu can't think about miles without first thinking about the stride and step count.

Gps has to be off, so use the treadmill mode.

The arms need to be swinging or at least not holding on to the support rails. 

First i would verify the step count accuracy, then we can adjust the stride.

These steps should get the miles closer.

The reason is that the Blaze while running on the treadmill has no way to measure distance. A person does not physically move. Fitbit therefore takes the steps, then multiples this count by the stride to guess at the dostance.

One problem is that as the pace of the walk/run changes, so does the stride.

@Laurel101 I was having the same problem until I adjusted my stride.

To get the most accurate stride I went through my last 3 treadmill runs.  I knew that I ran 3 miles each time even though my Blaze was giving me different readings.

This was a formula I found here on the community boards:

Stride = (miles x 5280) / steps

For me (3 x 5280) / 4,887

              15,840/4,887 = 3.24

I used the data from 3 treadmill runs and found my stride to be almost exactly the same each time so I adjusted my stride.  Now my treadmill workouts are very close to being perfect for distance.

Hope this helps!
