Turn any treadmill smart for more accurate training.
  • Features

    There’s a whole new way to run on Zwift thanks to the Runn™ Smart Treadmill Sensor from North Pole Engineering.

    The Runn™ easily installs onto the side rail of most treadmills. By using an optical speed sensor to track belt rotation speed, this revolutionary device broadcasts data directly back to Zwift via BLE and ANT+. What does this mean? It means you get the most accurate speed, distance, incline, and cadence data while running on Zwift, helping you level up every time you train.
