Overview
- Yomif Kejelcha won the 37th Media Maratón de Buenos Aires with a reported time of 56:50–56:51, which coverage says set a new men's half‑marathon world record.
- The previous world mark of 57:20, held by Jacob Kiplimo from March 8, 2026, was improved by roughly 30 seconds, according to multiple race reports.
- The men's podium was swept by Ethiopian runners, with Tadese Worku and Bereket Nega taking second and third, and the women's race was won by Ethiopia's Fotyen Tesfay in a new Buenos Aires course record of about 1:03:56–1:03:57.
- The event drew a record field of roughly 31,500 registered runners and required broad traffic closures across Palermo, Recoleta, Retiro, Monserrat and the Microcentro, disrupting city transit during the race.
- Top Argentine finishers used the fast field to post nationally notable results — Ignacio Erario ran just under 61 minutes — and organizers say the result reinforces Buenos Aires’s profile ahead of the international marathon in September and its push to attract more global events.
