Blaze inaccurate while being in treadmill

[LMGV2015]

Cross posted from the running thread. 

Does anyone else notice that their Fitbit (I have a Blaze) is off by almost 25.5 miles when running on a treadmill? Today while I ran on a treadmill it said I did 22 sets of stairs despite not setting my incline. At times I also feel like my Blaze isn't registering my steps fully. Anyone else have this issue?

My Blaze was purchased 11/16

Your stride is different on the treadmill than normal walking. That's why there is a difference

It's great to see you around @LMGV2015 and @WendyB thanks for stopping by.

Keep in mind that Fitbit trackers can potentially miss steps you're walking on a treadmill. For more information about this, you can take a look at the Will my tracker count stairs for treadmills and other exercise equipment? article and also adjust your stride length. 

I hope this helps, let me know the outcome.

Right. But on the treadmill, and my milestone pod, I'm still getting a good .25-.5 mile difference. 

My blaze is showing LESS mileage than what the treadmill/milestone pod are registering.

It'll be thinking your stride length is shorter than it really is. As it can't use GPS in doors it'll work out distance by doing steps x stride length.

You can set stride length in advanced options on the app.

Bear in mind this is never going to be 100% accurate though, as your stride length will vary with every step.

Thanks for the information @LMGV2015 and @CliffinKent for stopping by.

As our friend and I mentioned, please measure one more time your stride length. After this, test your Blaze.

Keep me posted.
