Mount Zoncolan has gained the nickname of the “Kaiser” among cycling fans, as the road ascending the mountain is extremely tough for any cyclist. Gradients often exceeding 15%, long straight sections and steep, narrow bends combine to make it extremely challenging, both physically and psychologically, even for well-trained cyclists.
