Rivers Sava and Danube meet in Belgrade and there is a nice promenade along the riverbanks where you can go for a run or simply enjoy the scenery. Starting near Savamala at the Brankov Bridge, you run around Kalemegdan, the Novak Tennis Center, the funny looking concrete tower (there is a gym there) until you reach Dorcol. The paths are in good condition, there is a bike lane and there are always people around. If you are in the mood, you can even cross Brankov bridge and run on the other side, all the way to Zemun.
