I am new to Zwift and do not understand how the system works in combination with a classic trainer. I have a cadence, speed and heart rate sensor connected to my computer.
Since I am using a classic trainer, the system does not get any information about the resistance level of my trainer (which I am able to set). But this information would be essential for computing the power data. Or is there any indication on the user interface which demands a certain resistance level of my trainer? This would make sense, because I had to let the system know which trainer I am using. Or do I always need to choose the highest resistance level? Yesterday, I started a test ride and was easily capable of riding with more than 300 watts with a heart rate of around 100 bpm. I guess this numbers are at odds with the reality.
What am I missing here?
