Overview
- Both cities will hold mass-participation races on Sunday, August 23, with Lima’s KIA Media Maratón de Lima & 10K confirmed for 21,000 entrants and Buenos Aires’ 37th Media Maratón reporting roughly 30,500–31,500 registrations in different outlets.
- Lima organizers completed kit pickup on August 21–22 at the Pentagonito and launched an official race app to provide live tracking for participants and spectators.
- Buenos Aires published full circuit maps and rolling traffic-closure schedules to manage street interruptions across central avenues, and the race will use wave and corral starts to reduce crowding at the 8:00 a.m. start.
- Elite fields headline both events: Buenos Aires lists world-class athletes including Yomif Kejelcha and top East African runners, while Lima serves as a national championship and qualification race with a $10,000 prize offered for a new Peruvian half-marathon record.
- Organizers are promoting new fan and runner features—Buenos Aires allows the first ~29,500 starters to print surnames on dorsals and issues two-piece magnetic medals, and Lima is rolling a multi-year medal collection and charity partnerships that channel funds to local social organizations.
