What racers and reviewers say
- Slowtwitch forum: 'Ironman Brazil - Up to get down?' (ezeocampo)Raced 2018 · forum · Positive
Four-time finisher (2015-2018) calls the race fast, friendly and of low-to-medium difficulty but less polished than bigger events. Swim usually calm with a short beach run mid-lap, bike is two 90 km (56 mi) laps with a couple of short climbs each way and avoidable drafting. Advises staying in Jurere or cheaper Canasvieiras.
Describes clear blue water, a wide two-lane highway with rolling terrain and views, and a fast but interesting run. Stayed in a cheap Airbnb in Florianopolis city; shops and bike shops nearby, though the taxi to Jurere is long. Found safety and roads good.
- Racecheck (Roberto W.)Raced 2016 · aggregator · Positive
Rates the race 4.6. Says the sea is usually calm, spectators are plentiful, and city logistical support is strong. Notes the entry fee is somewhat high versus foreign races.
- Racecheck (Holderbach)Raced 2015 · aggregator · Positive
Rates it 4.0. Training-day swim was choppy but race day was great; roads good, but packs formed on lap 2 and aid stations lacked gels. Temperatures ranged roughly 17-30 °C (63-86 °F) and the reviewer recommends extra days to see the island's beaches.
- TriRating: Ironman Brasil 2026 analysisRaced 2026 · article · Positive
Calls it another quick race in Brazil with one of the fastest bike adjustments ever there thanks to a tight lead group. The run was slower and tougher than usual, with several athletes fading after a fast ride.
