IRONMAN Curitiba
IRONMAN 70.3 Curitiba is on 21 March 2027, opening with a 1.9 km swim in the Passaúna Reservoir and finishing on a 21.1 km run inside Parque Barigui, where the finish line and the race village both sit.
The bike is a single 90 km loop, which is worth knowing if you dislike lapped courses and the traffic they create among slower and faster riders. It is also hilly rather than flat, and that is the honest read on this race: Curitiba sits on a plateau and the terrain around the reservoir does not stay level.
The altitude of the city keeps the temperature well below what the Brazilian coastal races deliver, so this is a cool-weather option in a calendar full of hot ones.
Curitiba has its own airport with connections through São Paulo, and the city is compact enough to manage race week without a car.
