The IRONMAN Buenos Aires 70.3 presents a demanding yet picturesque course, taking athletes through the breath taking landscapes of Buenos Aires, Argentina. The event starts with a two-loop swim in the tranquil Río de la Plata, the expansive estuary that delineates the border between Argentina and Uruguay.
After completing the swim, participants embark on a challenging three-loop bike route that explores the undulating hills and verdant areas around Buenos Aires. Beginning in the city center, the course extends southward towards the coastal city of Mar del Plata, weaving through the alluring neighbourhoods of Recoleta, Palermo, and San Telmo. Cyclists then loop back, passing through the city center once more before returning to the start point to finish the bike leg.
The running portion of the race, a 21.1-kilometer (13.1-mile) three-loop course, leads competitors along the picturesque waterfront of Puerto Madero. This redeveloped dockside area, celebrated for its contemporary architecture and fashionable dining spots, provides stunning views of the Río de la Plata, the city’s skyline, and the iconic Puente de la Mujer. These vistas serve as a powerful source of encouragement for athletes as they make their final push towards the finish line.
