Ines Papert and Caro North belong to the most famous and best professional alpinists. Both of them make their living from mountaineering, and usually they climb the highest mountains around the world, from Alaska to the Himalayas. Last summer, however, all their expedition projects fell through due to the worldwide pandemic. Therefore, the two of them set off together for the first time, to live an adventure on their own doorstep. They crossed Switzerland from east to west on their mountain bikes, climbing between Rätikon and Eiger, some of the country’s great walls on challenging routes.
