This is Berlin’s most important commercial street, akin to the Champs Elysees. The Ku’damm, as it is called, has been the heart of west Berlin, lined with cafés, clubs, fashion stores, car dealerships (nice looking ones) and restaurants. It is pleasant to run along this wide road, especially in the morning before it’s too crowded. Also a good night running option. A there and back along the main sections of the road is ~4.8 miles. Good options to continue south of Kurfürstendamm into the Wilmersdorf area and lovely Volkspark.
