"Traveling is a very subjective experience, a conspiracy between perception, imagination and physical constraint." By these words, Claude Marthaler reveals his total commitment in this art of living that he made his own. Pedal and enjoy this euphoria which carries and transports it, which makes him chain unreasonable flights and hallucinated puns. He delivers here a "velosophical" reflection that he transcribes with poetry and humor. "Traveling slowly is to meet quickly." This is the other secret of this incredible energy that he deploys: the happiness of meeting and sharing. For Claude, "getting on a bike, it's also riding all paradoxes". Fragility becomes a force, the indolent rhythm an accelerator. He thus gives the earth his true dimension, both immense and intimate. The right measure of the world.
