The start of the marathon was at Fælledparken and from there runners came down across the north end of the lakes and along, one block back from the lakes, before crossing over the lakes on Dronning Louise Bro. It was then straight on through Nørrebro to the railway station before heading west and south, down through to Frederiksberg on a zig zag route, to the harbour at Fisketorvet.

From there it was a long straight run - along the 02 - to Børsen and up to Kongens Nytorv and along Bredgade before swinging out to the east through Østerport to turn back down and back for the finish, back at Fælledparken.

Car traffic within the circuit was tightly restricted and at key points pedestrians could cross over into the inner city if there were appropriate gaps between runners or, at busy points, by temporary bridges.

The photograph is of runners was taken at Det Kongelige Bibliotek, Den Sorte Diamant / the Royal Library known generally as The Black Diamond. Here they are just over half way through the run but, at least, heading for home.
