The Belgrade Marathon is one of the biggest sporting events in Serbia. A group of enthusiasts came up with a plan to restore the race that existed in 1910 from Obrenovac to Belgrade. The first modern marathon in Belgrade took place on May 8, 1988. The track length of the original 1910 marathon was 23 km with several checkpoints. The track length of the 1988 marathon was 46.7 km, with the start and finish being in front of the Federal Parliament Building. Since 1990 the Belgrade Marathon has a standard 42.195 km length.
