The extreme athlete Jonas Deichmann takes on the challenge of crossing America in a duathlon. First he masters the impressive distance of 5,500 km by gravel bike from New York to Los Angeles. He then walks back to New York, completing an ultramarathon every day. He does not choose the fastest route, but follows small roads that lead him through breathtaking landscapes such as Death Valley, Monument Valley and the Rocky Mountains. On this adventure, he is exposed to the vagaries of the weather in all its facets. You can discover the equipment he wears in this RYZON collection.
