A dry, high-desert Argentine race — fast on paper, but wind and low humidity define the day.
Clear, calm swim in the Punta Negra reservoir surrounded by desert mountains.
Wide, smooth desert highway loops at altitude with long false flats and a constant, strong Zonda-style wind.
Flat run on closed roads through the reservoir valley, dry heat with very little shade.
Actual monthly averages from the last 3 years (Open-Meteo). Real race day may vary.
Water temp uses athlete-reported values first, then official race data, then the marine archive (sea swims, measured at the nearest offshore point). Values tagged est. are modelled from recent air temperature for lakes and rivers, where no observational data exists.
