Running is great! One reason for this is that you can run almost anywhere, whether in the snow or on the beach, in the forest or on the street, in the heat or in the icy cold. Running is always possible, sometimes faster, sometimes slower.
No matter where Jonas and I are, we always have at least a pair of running shoes with us. What a compass and map are for others, our running shoes are for us. We use them to explore cities and nature in a very intensive way. Give it a try! You will be amazed at what you will experience.
