Widely regarded as the toughest full-distance IRONMAN. Wind, heat, and elevation combine to test the strongest.
Two-loop swim in Playa Grande with a brief Australian exit.
Volcanic terrain with relentless wind and 2,500m of climbing across the island.
Three-loop run along the coast in Puerto del Carmen.
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.
