Why does Distance say “Speed Sensor Required”?
When you’re recording an Indoor activity there’s no way for Cadence to know how far you’ve traveled without a Bluetooth speed sensor connected.
Make sure to connect a Bluetooth speed sensor and set an appropriate wheel circumference in Settings > Gear > Bike > Wheel Circumference.
Cadence can then use the speed and size of the wheel to determine the distance traveled.
If you didn’t realize you’d set your activity to Indoor, simply tap the button to switch back to Outdoor. During an Outdoor activity Cadence will use the GPS sensor for distance calculation by default, or a Bluetooth speed sensor if the “Prefer Bluetooth Speed” option is set in Settings > Bluetooth Sensors.
