The story

Buenos Aires Half Marathon in Buenos Aires

Latin America's largest half marathon by field size, run through Palermo and central Buenos Aires since 1989, when it began as a single-sponsor race. The certified 21-kilometer course starts and finishes at Figueroa Alcorta and Dorrego and draws more than 20,000 runners in recent editions.

Buenos Aires' half marathon started in 1989 under a sponsor's name, the Media Maratón Adidas de Argentina, an idea credited to organizer Domingo Amaison, who wanted a 21-kilometer date on the city's sports calendar.

What is special

The part that makes it specific.

01

The place changes

With organizer-reported fields above 20,000, this is the largest half marathon field in Latin America, and its World Athletics certification since 2016 makes it a recognized target for runners chasing officially ratified times

02

The mystery stays covered

The race shares its exact start and finish corner with the city's full marathon but threads a distinct 21-kilometer loop through downtown avenues rather than the full race's longer route into La Boca

03

The city starts moving

What began in 1989 as a single-sponsor race has since outgrown that origin entirely

04

The water draws everyone in

The race traces to organizer Domingo Amaison, who launched it as the Media Maratón Adidas de Argentina, and because the field has grown so large, corral starts are now staggered to manage crowding at the shared Palermo start line
