One issue I am having is training on rollers.
I ride rollers, not a trainer. When I use my bike with a power meter it is not an issue. When I ride with my bike without a power meter, zwift gives me 400 watts when I am just soft pedalling. I once did a lap on watopia full gas and got all the KOMs and various jerseys. I then deleted the ride as it seemed ridiculous. I certainly would have been flamed by all the other users.
You can change the trainer type to rollers, but when I do that I can only max out at 100 virtual watts, it takes me 2 hours to do 1 lap.
Perhaps there would be a way to fix this? Perhaps KOMs could only be obtained by riders using power data.
I do have power on my race bike. However, I like to use my old retired junker for indoor training so I can minimize wear and tear on my good one.
