Cut-off map: which streets will be cut off by the Buenos Aires Half Marathon

The 37th edition of the Buenos Aires Half Marathon will take place this Sunday, August 23, with thousands of runners participating in the event. Due to the large number of participants, several streets in the city will be closed throughout the weekend, starting from Friday, August 21, and continuing until Sunday night. According to the Buenos Aires government’s advance notice, the marathon will affect neighborhoods including Monserrat, Microcentro, Retiro, Recoleta, and Palermo. As a result, multiple roads and avenues will be impacted during the event and when the participants pass through them. Starting Saturday, there will be a complete closure on the northbound lanes of Avenida Presidente Figueroa Alcorta, between Avenida Dorrego and Julio A. Noble, lasting until noon on Sunday. From early Sunday morning, closures directly related to the race route will begin. The race route follows a path similar to previous editions, beginning at the intersection of Dorrego and Figueroa Alcorta, moving along that avenue, and later proceeding via 9 de Julio and Avenida Independencia. The course continues through the central area of the city before ending at Paseo Colón and Avenida Libertador, with the finish line coinciding with the start point in the woods of Palermo. This year's edition marks a record-breaking turnout, with 30,500 registered participants, the highest number in the history of the competition. This represents a significant increase compared to last year’s 27,000 runners, adding 3,500 more participants than in 2025. When compared to eight years ago, when approximately 15,000 runners were registered, the growth is even more pronounced, nearly doubling the number of participants over that period. The race will begin at 8 a.m., covering a distance of 21,097 kilometers through various iconic points in the city. Among the participants will be international elite athletes and notable Argentine athletes. The Ethiopian runner Yomif Kejelcha, considered the second-fastest marathon runner in history, will compete alongside other prominent names such as Fotyen Tesfay, Florencia Borelli, Micaela Levaggi, Joaquín Arbe, and Laureano Rosa. For the first time, participants will have the option to print their surname and national flag on the numbers they wear during the race. Additionally, the medals awarded this year will differ from previous editions, being manufactured in Spain and composed of two magnetized pieces, according to information released by the organizers. The increased interest in the event has led to extensive preparations, with traffic restrictions already in effect in certain areas since Friday. These measures aim to ensure the safety of both participants and spectators while facilitating smooth movement around the race route. Authorities have emphasized the importance of these closures to manage the high volume of people expected in the affected zones. The event is anticipated to draw a large crowd, with many residents and visitors planning to attend. Local businesses near the race route have been advised to prepare for potential disruptions in customer flow due to road closures and increased foot traffic. Emergency services and security personnel will be deployed to handle any incidents and maintain order throughout the duration of the event. As the date approaches, officials continue to monitor the situation and make necessary adjustments to the logistics surrounding the marathon. They have assured the public that all precautions are being taken to minimize inconvenience while ensuring the success of the event. With the largest number of participants ever recorded, the 37th edition of the Buenos Aires Half Marathon promises to be a memorable occasion for all involved.
