Hello @Icyhot25, thanks for joining us, it's great to have you on board! 

If there's a big discrepancy in the distance measured by your Alta and what MapMyRun is showing, my recommendation would be restarting your tracker and monitor it for the next days to check if the accuracy improves. In case it doesn't, please reply to me with screenshots of the Fitbit app and MayMyRun showing the discrepancy so I can check this further. 

I hope this can be helpful, give it a try and keep me posted in case you need anything else!

 I have reset 2x with no change in the ALta performance.

Hello @Icyhot25, thanks for taking the time to reply, I hope you're having an excellent day! 

If you're still noticing a big discrepancy on the distance between Fitbit and MapMyRun, please follow the steps below to calculate your stride length and then add it to your Fitbit account:

1. Go to a track or some place where you're sure of the distance.
2. Count your steps as you walk across that distance, making sure you travel at least 20 steps.
3. Divide the total distance (in feet) taken by the number of steps to get your stride length.

After calculating your Stride Length, you can add it to your account by going to the Fitbit app > Account > Advance Settings > Stride Length. The Fitbit app calculates your Stride Length automatically based on your personal settings, but sometimes it's better to add it manually to get a more accurate reading.

I hope this can be helpful, give it a try and keep me posted in case you need anything else!
