Steep, steeper - Hegestrasse. I don't know if it really is the steepest street in anything, but it is steep! Apart from that, it is also really nice, you always have a beautiful view of the Ruhr valley (if you still have air to turn around and look). And another highlight: A small "side work" by the lock and helmet manufacturer Abus is located on Hegestrasse. Enough good reasons that make Hegestrasse a must for every Ruhrpott racing cyclist!
