About this race
Buenos Aires has earned its 'Paris of the South' comparison, and the marathon course proves it. The near-flat route (just 35m gain) runs through the wide tree-lined boulevards of Palermo and Recoleta, the Puerto Madero docklands development, San Telmo's cobbled tango streets, and the sweeping Avenida 9 de Julio — the world's widest street. October is Southern Hemisphere spring in Buenos Aires: 16–22°C, low humidity, light breezes off the Río de la Plata. These conditions, combined with the pancake-flat course, make Buenos Aires one of the most underrated PB opportunities outside Europe. Porteño crowd support is passionate, the post-race asado culture is extraordinary, and entry is extremely affordable by international standards.
