On 9 August 2026, Itaú BBA IRONMAN 70.3 Rio de Janeiro sends athletes into the waters of Copacabana, where a single-loop 1.9 km swim unfolds along one of the world’s most famous beaches before athletes transition at Forte de Copacabana. The 90 km bike leg heads along Avenida Atlântica and out toward downtown on closed city roads and coastal avenues, using long, mostly flat stretches past Botafogo, Flamengo and near Santos Dumont Airport, with the skyline and bays on full display. The three-lap 21.1 km run is based around Aterro do Flamengo and Marina da Glória, staying on smooth asphalt with gentle gradients and constant views of Guanabara Bay, Sugarloaf and the city’s hills. With warm but manageable winter temperatures, huge local support and a finish chute set against the harbour, it’s designed as both a performance race and a classic South American racecation.
