Ironman Calella-Barcelona 2027
IRONMAN Calella-Barcelona (3 October 2027) is Europe's most popular end-of-season race: a Mediterranean swim in Calella, a fast bike leg along the coast to Badalona, and a flat marathon between Calella and Pineda de Mar finishing on the beach. The course is marketed as one of the fastest on the continent, with winning times under 7h30. Early October weather is mild (average highs of 25°C, water around 22°C). The heat and wind ratings are editorial judgements based on available facts; times in the tables are rough estimates, not official data.

Indicative profile · Scheda automatica da fonti pubbliche (2026-11): da rivedere. The organiser publishes the final course in spring: this page updates.
Swim3.8 km
- Single 3.8 km lap starting and finishing on Calella beach.
- Irregular loop with long straights of 1,250 m and 1,550 m: pick your sighting landmarks carefully.
- Very clear water; average temperature 22°C (24°C in 2025, 21.5-22°C in 2024).
- Wetsuit almost certainly allowed: the organisers recommend bringing one (plus a spare).
- Jellyfish occasionally reported, but few.
Bike180 km · 750 m D+
- 180.2 km over 2 laps along the coast from Calella to Badalona, official elevation gain 750 m (course page: 774 m).
- New course billed as 'optimised for speed': almost entirely flat with two climbs of around 5% per lap.
- Heads up: athletes' GPS devices record more (1,000+ m); expect false flats and gentle rollers, not a perfect billiard table.
- The course is available on ROUVY so you can train on it in advance.
- Aero position and steady power management pay off big here: few surges, lots of average speed.
Run42.2 km
- 3 laps between Calella and Pineda de Mar, alternating seafront and urban sections.
- In 2024: a 1.6 km opening section through a park plus three 13.5 km laps along the coast.
- Almost flat: around 50 m of total elevation gain, with the odd overpass and gentle gradients.
- Aid stations roughly every 2.5 km: water, electrolyte drink in cups, Maurten gels (with/without caffeine), bananas, oranges, salty snacks.
- Beach finish: big crowds and a proper end-of-season atmosphere.

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.
Is the wetsuit allowed? Almost certainly yes: the average water temperature is 22°C (24°C in 2025, 21.5-22°C in 2024) and the organisers recommend bringing one, plus a spare. The final decision is announced on race day. Is the bike course really that fast? Yes, with a caveat: official elevation gain of 750 m (774 m on the course page), two coastal laps with two 5% climbs per lap. Athletes' GPS devices often record over 1,000 m due to false flats and rollers. It's still a PB course if you hold steady watts. What's the marathon like? Three flat laps between Calella and Pineda de Mar (in 2024: a 1.6 km opening section plus 3 laps of 13.5 km), around 50 m of total elevation gain with the odd overpass. Aid stations every 2.5 km and a beach finish. What's at the run aid stations? Water, diluted electrolyte drink served in cups, Maurten gels with and without caffeine, bananas, oranges and salty snacks, roughly every 2.5 km. Test them in training or bring your own products. What weather should I expect in early October? Mild conditions: around 16°C on race morning (2024 data), average highs of 25°C with peaks of 27°C. Plan layers for the cool morning on the bike and heat management on the afternoon run. Where's the best place to stay? In Calella: most hotels are within 3 km of the village and the single transition area at Camp de Mar, all walkable. Visit Barcelona separately, before or after the race. How long do transitions take? The transition area is big: in 2024 some athletes recorded a 15-minute T1 and a T2 of over 11 minutes. Do a recce the day before and budget 20-25 minutes total. Can I ride the bike course before the race? Yes, virtually: the course is available on ROUVY. Use it to memorise the two climbs per lap and the spots to push or recover. Are there jellyfish in the swim? A 2024 report mentions a few, but not many. The water is described as flat and crystal clear, with excellent visibility. What are the cut-off times? Not listed in the sources consulted: check the athlete guide on the official race website before planning your splits.

Preparation tips
What to do from today to race day
In 2024 one athlete had loose cockpit bolts after reassembly: check torque settings or visit a mechanic before check-in.
On course you'll find Maurten gels and diluted electrolyte drink in cups: test them in training or bring your own.
Official elevation gain is 750 m but GPS devices record more: plan gearing and pacing for false flats and two 5% climbs per lap.
Average water temperature 22°C: the organisers themselves recommend a wetsuit plus a spare. Don't leave logistics to the last minute.
The bike course is available on the platform: use it to memorise where to push and where to recover.
Single transition area
T1 and T2 are both at Camp de Mar, an artificial turf football pitch next to the beach where the swim finishes.
Accommodation in Calella
Most hotels are within 3 km of the Ironman Village and the transition area: everything is reachable on foot or by bike.
Barcelona separately
Common advice: stay in Calella for the race and visit Barcelona separately, before or after.
Long transitions
Big transition areas: in 2024 transition times exceeded 10-15 minutes. Do a recce the day before.
