Course Guide
Swim: The two-loop ocean swim takes place in the calm, sheltered waters near Jurerê Internacional beach. Water temperatures in late May sit around 22°C, making it borderline wetsuit-legal. The course is well-marked and the calm conditions make it forgiving for athletes nervous about open water starts.
Bike: The 180km bike course is widely regarded as one of the fastest on the IRONMAN circuit. Predominantly flat and aero-friendly, the route loops through Santa Catarina island with only four short, sharp climbs per lap. Athletes who can hold aero position well thrive here — expect course record attempts when conditions align.
Run: The four-loop run through Florianópolis city is flat and fan-friendly, with great crowd support throughout. The layout means you pass the finish line multiple times before crossing it — mentally challenging but motivating. Expect a lively atmosphere with Brazilian spectators out in force.

Age Group Considerations
