Mileage incorrect on sense

[Lizmarvan]

I just got a new Fitbit Sense today to replace my ionic and the mileage is way off. The steps are correct but it says I have only gone 1.5 miles and done 8000 steps. Last week I did the same number of steps and had about 3 miles. Both times I did about 2 miles of that on a treadmill.

I have still not figured this out. I checked my stride length and did the math with my steps and yesterday was 2 miles wrong for my total miles. The only issue I can think of is the treadmill so I will walk outside today and see if the mileage is correct. If it is the treadmill does anyone have any ideas on how I can fix this?

Yesterday I just did all outside walking and everything was correct with my steps and mileage. I just walked a mile on the treadmill and even set the exercise app on my Fitbit to treadmill and my mileage is off. Anyone have any ideas?

I have figured out the problem but do not know how to fix it. I did exactly 1 mile on the treadmill and ran the treadmill exercise app on fit bit the entire time. The app only shows I walked .44 miles. How would I fix this? It is accurate for normal walking

I am having the same problem. I have my Sense on the treadmill option and it calculates my distance as half of what my treadmill says. Has anyone come up with a way to fix this yet?

Has anyone figured this out? I'm not on the treadmill but mileage is way off. It says I walked over 8k steps but only a little over a mile. I ride my peloton for over 10 miles a day and it doesn't track any of those miles.

Today I went on a 2 mile walk outside. I set it to walk so I could get my stats. It only logged 1 mile. I had checked my route on a route planner and it is just over 2 miles. I think it is a problem with those group of settings not registering right. In my case I don't think the gps is registering right, because the steps look right.

ok so let me start by saying I hope you all were honest when setting up your account for the fitbit watch what i mean by this is you gave correct age correct height and weight no exaggeration no guessing the absolutely real info if so then the watch not calibrating correctly you can adjust this yourselves by

1. In the Fitbit app, tap the 'Account' icon which should be the icon with your profile photo if you've used one. Then scroll down to 'Activity and Wellness' and tap.

2. Next, select 'Exercise' and you should see an option for 'Stride Length'. If you haven't tweaked this before, it's likely set to automatically track your steps, adjusting whenever you've ran with GPS enabled depending on your device's support.

3. If you toggle it off, you'll be able to set this manually.

Also to learn how to measure your stride length both for walking and running this will help make it as accurate as possible. here some info i found how to do that.

Before You Begin:

Find a flat, measured route. I highly recommend using a running track. Running tracks are commonly found at local schools, colleges, and parks. Often, if the track isn’t in use for a team practice or class, community members are welcome to use it. Contact your local school, parks and recreation service or college if you are unsure whether this is an option for you. If a track is not available, try a route where you know the distance or use a treadmill. Another option is to use a GPS app to calculate the actual distance; this is my last choice option because I find that my phone GPS app varied from the actual distance when I tested it on a measured running track. Phone GPS isn’t 100% accurate, but it would likely give you a pretty close estimate.
Be sure and wear your Fitbit device in whatever manner is typical for you. This test will calculate the distance you covered per Fitbit counted step.
Stage One Instructions: At The Track…

Stand still at the starting point, push the Fitbit timer or stopwatch button (for devices that track sleep, it is the exact same function. (Zip users, take note of your step count before you start and check it again when you finish. ) Stand still for a couple of seconds to make sure no steps are counted before you begin.
Walk your lap using your most natural pace. A longer walk can be more accurate. I found 1 mile ideal, but shorter distances can work too.

3. As soon as you reach the finish point, stop stepping. Press the timer button to end your record. Wait a few seconds to make sure no extra steps are included.
Repeat the test running or briskly walking (if you won’t be using the Fitbit to estimate your running distance).

Stage Two Instructions: When You Get Home…

Sync your Fitbit. Then go to your Fitbit activity log page. After your Fitbit device synchs to your account, you should have two activity records, one for walking and one for running.
Plug the steps that Fitbit recorded into the formula:
Formula to Calculate Average Fitbit Stride Length in Inches:

Sorry metric users, this formula is based on inches and miles. I know you will be able to do the appropriate conversion yourself…
63360 * actual miles / by Fitbit counted steps = average stride in inches

Find the settings option in your Fitbit dashboard, it is in the upper right-hand corner.

Clik on the Gray Gear Icon to access your settings.

Now enter your stride length. Fitbit accepts decimal points in the stride settings. I personally found my distances to be more accurate when I entered my stride length rounded to one decimal point as opposed to rounding it to a whole number. I entered my stride length in feet and inches.

I have been much happier with the accuracy of my Fitbit on distance, pace, speed and activity level estimation since I calibrated my stride length settings. It is important to remember that for most of us, our stride is not static. It may vary by how tired we feel, the ground we cover, what shoes we are wearing and other factors. It also may change over time, so it might be a good idea to retest as you notice changes in fitness level or walking and running technique.
