Ironman 70.3 Aracaju 2026
IRONMAN 70.3 Aracaju (Sergipe) takes place on November 29, 2026 in Brazil: a river swim at the mouth of the Vaza-Barris, a flat three-lap bike and a half marathon along Atalaia Beach. The course is billed as fast, but the climate is tropical: air up to 30°C and water around 26-27°C, almost certainly non-wetsuit. The wind index is neutral due to lack of data. The split times listed are rough estimates, not official data.
Course
Three legs, three different races
Indicative profile · Scheda automatica da fonti pubbliche (2026-11): da rivedere. The organiser publishes the final course in spring: this page updates.
Swim1.9 km
- 1.9 km in the river at the mouth of the Vaza-Barris, with views of the Orla do Pôr do Sol.
- Water averages 26°C (some sources say up to 27°C): above the 24.5°C wetsuit cutoff, so almost certainly a non-wetsuit swim.
- Number of laps not published: check the athlete guide before race day.
- Advice from the sources: train in open water before race week.
Bike90 km · 845 m D+
- 90 km over three laps, billed as flat and fast.
- Elevation: the official page lists around 845 m, another source only 377 m (max gradient 5.2%). The data conflict, but treat the course as flat.
- Aero position and steady pacing are the priorities on this type of course.
- Three laps: watch out for lapped-athlete traffic in the middle stages.
Run21.1 km
- 21.1 km along Atalaia Beach, with spectators close to the athletes.
- Minimal elevation: 60 m per the official page (82 m per another source). Flat.
- Number of laps not published: verify in the official documents.
- Humid heat is the key variable: manage pace and cooling from km 1.

Mais um ano …Reviews
Who raced it, what they say
At launch, pages start from syntheses of public race reports, declared as such. Verified reviews come from athletes who receive the invite within 7 days of the race, with the activity recorded on their device.
Structured fields: finish and leg times from your device, wetsuit yes/no, gear, perceived temperature, what you'd do again and what not, «I'd race it again». Free text is the race report. The linked activity makes it verified without exposing personal data.
The form appears here after the race, for those who connected a device or appear in the official results.
Can you wear a wetsuit? Almost certainly not: wetsuits are only allowed with water at 24.5°C or below, and the average here is 26-27°C. Be ready to swim in a tri suit or swimskin; the official measurement is announced on race day. Is the bike course really flat and fast? Yes, it's billed as flat over three laps. Elevation data conflict between sources (about 845 m per the official page, 377 m per another source), but either way treat it as a fast course to ride in an aero setup. How much does the heat matter in this race? It's the key variable. The 2025 edition was raced at around 30°C and some reports mention athletes needing assistance at the finish line due to exhaustion. Acclimatization, conservative pacing and cooling at every aid station are mandatory. How many laps are the swim and the run? The number of swim and run laps isn't published in the sources consulted: verify it in the official athlete guide. The bike is three laps. Is the swim in the ocean? No, it's in a river: you swim 1.9 km at the mouth of the Vaza-Barris, with views of the Orla do Pôr do Sol. The recurring advice is to train in open water before race week and do a familiarization swim on site. What's the cutoff time and how much is registration? Neither figure is listed on the pages consulted: check the official site and the athlete guide after registering. How do I handle getting my bike to Aracaju? Carefully: a domestic connection within Brazil is almost always needed, and one 2025 athlete had her bike lost by the airline just days before the race. Book the bike as special luggage on all legs, use a tracker and arrive with 3-4 days of buffer. Is the race suitable for bringing family and supporters? Yes: the run along Atalaia Beach lets spectators follow athletes up close, and the three bike laps multiply the pass-bys. Aracaju also offers beaches, rivers and mangroves for the non-race days. When should I arrive in town? At least 3-4 days before, both to absorb potential baggage delays and to start acclimatizing to the humid heat. If you're coming from a cold climate, the more days the better.
The Q&A is fed by reviews and the rulebook: every answer says where it comes from.
Preparation tips
What to do from today to race day
It's the explicit advice from the sources: a non-wetsuit river swim demands specific confidence.
The half along Atalaia Beach is flat but hot: conservative first kilometers, ice and water over your body at every aid station.
Sources conflict (845 m vs 377 m on the bike): either way, set up for a flat, fast course.
Simulate sessions in the hot hours and decide in advance how much to drink and how much salt to take per hour.
Race venue
Aracaju, state of Sergipe, Brazil: an area known for beaches, rivers and mangroves. Swim at the mouth of the Vaza-Barris, run along Atalaia Beach.
Pre-race information
The official site has dedicated sections for pre-race info, race week, accommodation and transport: check them after registering, as details weren't published on the pages consulted.
Date
November 29, 2026: a hot time of year in the southern hemisphere — plan your acclimatization if you're coming from a cold climate.

Wheels for this course
A rule of thumb from this course: 9.4 m of climbing per km and low wind exposure. It is guidance, not a count. (hilly)
Front wheel
40-60 mm deep
Rear wheel
50-60 mm. Use a disc only if the descents are not technical and the weather is stable
Tyres
28-30 mm, tubeless if possible. Choose pressure by weight and road surface, not by habit.
Check the weather and the wind forecast on race week: on windy days, drop a depth step on the front wheel.
Race kit
Fuel and pack, nothing forgotten
Work out carbs, fluid and sodium for this course, split into bottles, gels and bars, then tick off everything to pack from passport to Vaseline.
Start at 60 g/h if you have not trained your gut, 80-90 if you have. Never try new products on race day.
Hot course: drink to thirst plus the amounts shown, favour salt, and use ice and water on the run.
Before the race
Carb load
560-700 g carbs per day for the last 1 day(s)
Breakfast, 3 h before
70-140 g carbs, low fibre, familiar food
On the bike 2:45
Every 20 min · 23 g carbs and about 233 ml
On the run 2:05
