Action needed if you use Fitbit: Please connect to Google Health before the 30th of September 2026 to ensure your Fitbit activities keep syncing.
The Fitbit app is now Google Health, and your existing connection needs to be re-established through it. See the "Reconnecting after the Google Health change" section below for the steps.
Overview of Fitbit
Fitbit is a health and fitness brand known for its wearable tracking devices and companion app. Within the app, you can monitor metrics like daily steps, heart rate, and sleep, set wellness goals, and share milestones with friends.
By connecting Fitbit to Runna, the activities you record on your Fitbit sync back into the Runna app. That means your actual runs line up against your planned workouts, so you can see how your training is going in one place.
Compatible Fitbit Devices
Any Fitbit device with GPS capabilities will work with Runna:
Fitbit Ionic
Fitbit Versa 3 and up
Fitbit Sense
Fitbit Charge 4 and up
Pairing With Fitbit
To pair your Runna app with Fitbit, head to your Runna Profile and tap Connected Apps. Next, tap Connect Watch, then select Fitbit.
You'll be prompted to sign in to your Fitbit account and accept permissions. Once accepted, your Fitbit connection will show on the Connected Apps screen.
What Syncs, and How
When you record a run on your Fitbit, it syncs back into Runna along with your heart rate, pace, distance, and calories. Once it's in Runna, you can link it to the planned workout it matches.
Troubleshooting
Most Fitbit syncing questions come down to a few things. Here's how to get your activities back into Runna.
My run didn't sync into Runna
Open Fitbit.This is the first thing to check. Open the app and give it a moment to update.
Check the date on the activity. Runna links activities to the day they were recorded. If the date or time on your Fitbit is off, the run may not line up with your planned workout.
Reconnect the connection. If it still hasn't appeared, go to Profile → Connected Apps, disconnect Fitbit, then reconnect it.
Link it manually. If the run has synced but hasn't attached to your planned workout, open the workout in Runna and use Link Activity to attach the correct run.
My heart rate, pace, or distance isn't showing
Heart rate, pace, distance, and calories all sync from Fitbit, but they rely on the data permissions you granted when you connected. If any of these are missing:
Open Fitbit and check that data permissions are switched on for the activity you're looking at.
Open Fitbit so the latest data syncs across.
If it's still missing, disconnect and reconnect Fitbit in Runna to refresh the permissions.
I've got a duplicate or an activity with the wrong distance
Occasionally an activity can appear twice or import with a distance that doesn't match the run you did. You can remove the incorrect version in your Activities tab so it doesn't affect your training data. If an activity won't delete or is skewing your plan, contact us through in-app support and we'll sort it out.
Fitbit Limitations
Since Fitbit is a lifestyle and activity tracker rather than a sports watch, Runna can't send your prescribed workouts to a Fitbit device. This means you won't get live, guided coaching during your workouts. You'll guide yourself using what you see in the Runna app, and your Fitbit will sync the run back afterward.
