The Maratón de Rosario is Argentina's national marathon championship race, held each June on the banks of the Paraná River in the birthplace of the Argentine flag. Known locally as the 42K Rosario, the flat Pampas course starts and finishes at the iconic Monumento a la Bandera — a colossal national flag memorial that towers over the city's waterfront — and winds through the tree-lined Boulevard Oroño and the expansive Parque Independencia before tracing sections of the scenic Costanera riverside promenade. Held over Flag Day weekend, the race draws competitive Argentine runners alongside recreational participants in what has become one of the country's most prestigious road races. The championship status elevates the competition significantly, with national title contenders pushing the pace at the front. June in Rosario means mid-winter conditions — crisp mornings around 5-14°C — which are excellent for marathon racing on this pancake-flat course through Argentina's third-largest city. With approximately 2,700 runners and passionate local spectators, the atmosphere is intimate but spirited. A medical certificate dated within 30 days of race day is mandatory for all participants, as is standard for Argentine road races. Rosario's excellent steak restaurants, affordable hotels, and riverside cultural scene make it a rewarding destination.
