Getting Your Exercise Load Estimate
Before you can view your exercise load estimate, you must put on the heart rate monitor, install the power meter, and pair them with your device (Pairing Your Wireless Sensors).
If your device was packaged with a heart rate monitor, the device and sensor are already paired. For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile), and set your maximum heart rate (Setting Your Heart Rate Zones).
NOTE:
The estimate may seem inaccurate at first. The device requires a few rides to learn about your cycling performance.
