Treadmill Sensor Overview

The Runn treadmill sensor connects to your treadmill and transmits speed, distance, and cadence directly to the Charge Running app through a Bluetooth connection. This allows you to run hands-free and track speed and distance with significant accuracy. If you are don’t have one and are interested in purchasing it, you can find it in our shop.

General Installation

  1. When mounting the treadmill sensor, make sure you have the sensor placed over the top of your treadmill belt, and only has between 1/4″ and 1/2″ separation from the moving belt.

  2. Firmly attach the reflective stickers to the treadmill belt with at least 18″ of separation between each sticker

  3. Calibration: The sensor is individually calibrated to the correct speed when it leaves the factory, and registers distance based on the belt speed of your treadmill. This may cause your treadmill display to show a distance different than what is being read by the sensor (and sent to the Charge Running app). Since the treadmill sensor is significantly more accurate than your treadmill, it’s not advised to recalibrate the sensor. You can choose to calibrate it to your treadmill if you would like, but understand that the registered distance may no longer be accurate.

Connecting to the Charge Running App

  1. Turn the treadmill sensor ON (double tap the button on the side of the sensor)

  2. NOTE: The treadmill sensor has a built-in battery which uses about 4% for each Charge Running class you join. You can choose to leave the sensor plugged into power at all times, or plug it in to an outlet to recharge when needed.

  3. Open the charge app and navigate to Profile > Settings > Integrations & Permissions

  4. Tap ‘Runn Treadmill Sensor’ to connect

  5. It will prompt you to allow for Bluetooth access, which is required to receive data from the sensor – Press OK

  6. Once connected, under ‘Runn Treadmill Sensor’ it will display ‘Runn XXXXXX connected’ when successfully paired

General Use / Troubleshooting

  1. When the device is powered on, it will generally connect to your phone immediately, and require no additional input before joining into a class. If you switch to a different phone, go into Profile > Settings > Integrations & Permissions and make sure it shows ‘Runn XXXXXX connected’ to know it’s connected to your phone.

  2. If you do not see that it’s connected, tap ‘Runn Treadmill Sensor’ when It’s powered on, and it will reconnect.
