IRONMAN Florianopolis
IRONMAN 70.3 Florianópolis on 18 October 2026 races on the island: a 1.9 km ocean swim, 90 km on the coastal roads and 21.1 km back along the shore.
Florianópolis has been a triathlon town for decades and the course reflects local knowledge rather than a tourist route. The swim is a genuine Atlantic beach start with surf to get through, and the bike rolls between the island's beaches, with the short climbs doing the damage.
October is spring in Santa Catarina. That means warm rather than hot, and it means changeable. This stretch of coast gets fast-moving fronts off the ocean, so a calm sea on Friday tells you nothing about Sunday's swim.
If you are flying in from Europe or North America, note that this is a late-season race for you and an early-season one locally. The field around you will be sharper than the date on the calendar suggests.
