Yes my trainer is set at 100% therefore I am getting the full effect of the 16% and I can feel it.
But my local mountain - it is THE mountain for me - my most formidable opponent lol - it has a few sections of 25% +. And I wanted to know how I could prepare myself for that using the trainer.
Unfortunately it is not always opened to cyclist else I would go out and train on it. I don't know other places I could go with my road bike having the same kinda 25%+ gradients.
