Adapts to your fitness, schedule & recovery every week.
Expect high humidity and temperatures reaching 30°C or higher under intense tropical sun. Prioritize early cooling by utilizing cold water at aid stations, wearing a white race suit, and applying ice inside your kit if available.
Fuel & hydration
Due to extreme sweat rates in the humid tropical climate, aim for 60 to 90 grams of carbohydrates and 750 to 1000 mL of fluid per hour. Crucially, carry and consume extra sodium and salt tablets to prevent cramping.
Pacing
Avoid over-biking into the strong coastal headwinds, which can easily ruin your run. Save matches on the bike segment so you can maintain a steady, sustainable pace on the scorching and humid beachfront run.
Gear & logistics
Arrive a few days early to acclimate, staying along Avenida Beira Mar for convenient transition access. Opt for a mid-depth front wheel to maintain stability in gusty winds, and use high-quality mineral sunscreen before the race.
Frequently Asked Questions
What is the water temperature and wetsuit policy for the Itaú BBA IRONMAN 70.3 Fortaleza swim?
The water temperature in Fortaleza averages between 26°C and 28°C (79°F to 82°F), which means the swim is non-wetsuit legal. You will be swimming in warm ocean water, so you should prepare your gear and race strategy accordingly.
What conditions should I expect during the swim at Praia de Iracema?
The swim consists of a single-loop 1.2-mile (1.9 km) ocean course with a rolling start at Praia de Iracema. Because of consistent coastal winds, chop and ocean swells are highly common, and you may encounter mild ocean currents that can affect your sighting and pacing.
