Belgrade, SN · Saturday 4 July 2026
The 37th Comtrade Belgrade Marathon takes runners through Serbia's capital city in July 2026, offering a summer racing experience in one of southeastern Europe's most dynamic urban centres. Belgrade sits at the confluence of the Danube and Sava rivers, and the race course weaves through a landscape that blends historical neighbourhoods, riverside paths, and the city's modern districts. The setting captures the character of a Balkan city that has continually reinvented itself, providing runners with varied scenery as they progress through the course. The marathon follows a trail surface across moderately hilly terrain, which means you should expect consistent elevation changes rather than a flat, fast course. The 218 metres of elevation gain distributed throughout the 42.2 kilometres keeps the legs engaged throughout, and the range from 68 to 137 metres above sea level indicates rolling sections without dramatic climbs. Trail running on this kind of undulating course demands a different pacing strategy than road marathons. Runners will need to manage effort on the climbs while taking advantage of descent sections to recover, and footwork becomes more deliberate than on asphalt. The terrain character suggests this is a race that rewards steady effort and good hill sense over pure speed.

37th Comtrade Belgrade Maraton is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
