For runners who prefer to train on a treadmill or an indoor track, COROS offers Indoor Run mode to track workout data such as pace, distance, heart rate and more.
Getting Started
-
Maintain a steady pace. When running without a foot pod, your watch relies on a pace-cadence model. Sudden or frequent pace changes can create inaccuracies. For interval workouts, consider using Manual Speed to input your exact pace.
- From the Start screen of Indoor Run mode, scroll down and select Manual Speed. Enter the current speed of the treadmill.
- If you change pace during your workout, make sure to manually change the speed on the watch as well. Press the dial to pause your run, then scroll down to Speed or Grade to adjust the settings. Alternatively, without pausing your run, long press the Back button to open the Toolbox menu and scroll to Activity Settings. Select Speed or Grade to adjust the settings while your activity is tracked in the background.
- Use a foot pod for maximum accuracy. Devices like the COROS POD 2 measure foot motion directly, providing the most reliable pace and distance indoors.
- Calibrate after your run. At the end of the workout, your watch may ask you to confirm the total distance. Entering the correct value helps refine the pace-cadence model for more accurate tracking in the future.
Recalibration Support
It can be challenging for GPS watches to accurately track your run while indoors, due to the limited satellite signal. Thankfully, our watches utilize cadence to estimate pace with the help of a powerful cadence-pace model. With this model, the watch can estimate pace when you are running at different cadences to provide a more accurate representation of the total distance covered during your workout.
COROS watches estimate pace using cadence and a powerful cadence-pace model. If your pace seems inaccurate, you can rely on the post-workout distance calibration feature. After you enter the corrected distance, your watch will update the cadence-pace model to improve future indoor pacing accuracy at all cadence levels.
For eligible indoor runs, your watch will automatically prompt you to confirm the total distance before saving. Calibration is supported up to +/- 25% of the distance recorded by the watch. An indoor run qualifies if:
- No manual speed was selected
- A structured workout or training plan was not used
- The recorded distance is at least 1 km
Please note, the distance calibration for Indoor Runs does not apply to 3rd party apps. Often, they rely on their own algorithms to recalculate distance, pace, and other metrics before displaying the data to you. You may need to adjust the distance manually on 3rd party apps if desired.
