IRONMAN 70.3 Mallorca is one of Europe’s biggest and most recognisable middle-distance races. The 2027 edition is currently listed for Saturday, May 8, 2027 in Port d’Alcúdia. Athletes swim in the Bay of Alcúdia, ride a demanding 90 km loop through the Tramuntana foothills and finish with a flat three-loop half-marathon along the coast.
IRONMAN 70.3 Mallorca is not a flat 70.3. The swim is generally calm and fast, but the bike includes around 850 m of elevation gain and one major climb into the Lluc / Tramuntana area before a long descent and flatter return. The run is much quicker: 21.1 km over three flat loops in Port d’Alcúdia. In 2026, the median finisher completed the race in about 6:02.

Is IRONMAN 70.3 Mallorca a fast course?
The answer depends on the discipline.
The swim is usually quick because Alcúdia Bay is relatively sheltered. The run is also fast because it is flat and repetitive. The bike is what separates Mallorca from a typical “PB course.” The official route map lists approximately 850 metres of climbing, with the hardest climbing concentrated in the first half of the ride.
That means athletes who are strong climbers and confident descenders can race very well here, while riders who train almost exclusively on flat roads may lose more time than expected even if their FTP is good.
Think of Mallorca as fast swim + demanding bike + fast run. The bike decides how much of your running fitness is still available in T2.
IRONMAN 70.3 Mallorca swim course
The race begins with a 1.9 km single-loop swim in the Bay of Alcúdia. Recent athlete guides use a rolling start, with athletes self-seeding by expected swim time.
The bay is usually calmer than an exposed ocean swim, and the water is shallow and clear near the beach. That makes the swim one of the more approachable parts of the race, although a field of more than 2,500 athletes can still create congestion around the early buoys.
What to expect in the swim
- Single-loop 1.9 km course.
- Rolling start in recent editions.
- Salt water in Alcúdia Bay.
- Typical early-May water around the high teens Celsius.
- Latest published swim cutoff: 1 hour 10 minutes.
The 2025 athlete guide expected water temperatures around 16–18°C, making wetsuits common. Race-day wetsuit rules still depend on the official measured temperature, not the historical average.
Seed yourself honestly, settle quickly and use legal drafting. Saving two minutes in the first 500 m is rarely worth starting the bike with an unnecessarily high heart rate.
IRONMAN 70.3 Mallorca bike course: 90 km and around 850 m climbing
The bike is the defining feature of this race.
The latest official map shows a single-loop 90 km course leaving Port d’Alcúdia, heading toward Port de Pollença and Pollença, then climbing inland toward the Lluc area before descending back toward flatter roads through central and northern Mallorca.
The official elevation profile shows the course rising sharply between roughly 20 and 35 km, reaching around 600 m above sea level before the long descent. After that, the final part of the race is much flatter and faster.
Bike-course breakdown
| Section | What to expect | Best approach |
|---|---|---|
| 0–20 km | Fast roads leaving Alcúdia and approaching the foothills | Stay controlled; do not “bank” time before the climb |
| 20–35 km | Main sustained climb toward the Tramuntana / Lluc area | Cap power and avoid repeated threshold spikes |
| 35–50 km | Long technical descent | Prioritise line choice and control over marginal aero gains |
| 50–90 km | Faster, flatter roads back toward Port d’Alcúdia | Return to aero position and steady race power |
The climb matters—but the descent matters too
Many athletes focus only on the uphill section. That misses half the difficulty. The descent after the high point is fast and includes technical turns. A strong climber who is uncomfortable descending can easily give back much of the time gained uphill.
If you live somewhere flat, include descending practice before race week if possible. Indoor training can build the engine, but it cannot teach braking points, corner entry speed or confidence on mountain roads.
Use our Half Ironman Bike Pacing Strategy for power targets and intensity guidance.
Your speed can be very low on the climb and very high on the descent at the same overall race effort. Power, heart rate and RPE are much better pacing anchors than trying to hold one km/h target.
IRONMAN 70.3 Mallorca run course
After the mountainous bike, the run is comparatively simple.
The official run map shows a 21.1 km course over three loops around Port d’Alcúdia. It is flat, close to sea level and spectator-friendly, with repeated passes near the main race area.
Why the run is fast
- Very little elevation.
- Three loops make pacing easy to monitor.
- Frequent aid-station access.
- Strong spectator support near the beachfront.
- No major hills late in the race.
Why the run still goes wrong
- Too much power on the bike climb.
- Underfueling while descending or concentrating on bike handling.
- Starting the first run loop at open half-marathon pace.
- Heat exposure on an open coastal run if race day is warm.

2026 result data from TriTimes. Transition time is included in overall finish time but not shown as a separate row here.
The median bike split is noticeably slower than on flatter European 70.3 courses, which reflects the climbing and descending demands. The run median remains comparatively strong because the half-marathon course is flat.

Estimate your IRONMAN 70.3 Mallorca finish time
Mallorca’s hilly bike course can make generic 70.3 finish-time estimates misleading. Use our Triathlon Race Time Calculator and select IRONMAN 70.3 Mallorca to build a more course-specific estimate from your expected swim, bike, run and transition performance.
Weather and race conditions
Early May on Mallorca is usually mild, but the island can still produce very different conditions between the coast and the mountains.
The swim and run may feel calm and warm at sea level while the bike climb is cooler, windier and more exposed. Historical weather for race week typically sits around the mid-teens to low-20s Celsius, but hotter days are possible.
Prepare for
- Cool-to-mild swim conditions.
- Crosswinds in exposed mountain sections.
- Temperature changes between sea level and the high point of the bike.
- Potentially warm sun on the run.
- Fast descending on dry or wet mountain roads.
Travel and where to stay
The race is based in Port d’Alcúdia in northern Mallorca. Most international athletes arrive through Palma de Mallorca Airport and travel north to Alcúdia.
For race convenience, staying in Port d’Alcúdia is hard to beat. The swim start, transition and run course are all concentrated around the resort area, which reduces race-week transport stress.
What to prioritise when booking accommodation
- Walking or easy riding distance to transition.
- Bike-friendly hotel policies or secure storage.
- Early breakfast options.
- Simple access to race check-in and expo.
- Quiet enough location for sleep despite the busy resort atmosphere.
Mallorca is a major cycling destination, so bike rentals, mechanics and cycling-specific hotels are easier to find than at many other destination races.
How to train specifically for Mallorca
The best preparation is not simply “more climbing.” You need enough climbing ability to ride the mountain section efficiently without sacrificing the run.
-
Build sustained climbing power
Use 10–30 minute tempo, sweet spot and threshold intervals rather than only short hill sprints.
-
Practise controlled power over changing gradients
Avoid turning every steep ramp into a maximal effort.
-
Improve descending confidence
Cornering, braking and line choice matter on the long mountain descent.
-
Run well after climbing
Brick sessions should include race-power work before the run, not just easy spinning.
-
Fuel on technical terrain
Practise taking carbohydrate before and after harder sections so nutrition does not disappear when the road gets busy.
Use Sweet Spot Training, Threshold Cycling Workouts and Half Ironman Nutrition Plan when building the block.
Our 20-Week Beginner Half-Distance Triathlon Training Plan provides a complete swim, bike and run structure that can be adapted for a hilly 70.3 such as Mallorca.
Simple race-day pacing strategy
| Discipline | General approach | Main mistake |
|---|---|---|
| Swim | Relax early, draft legally and use the calm water efficiently. | Starting too hard in a large rolling-start field. |
| Bike climb | Cap power and ride below the effort you could sustain in a standalone climb. | Racing other athletes uphill. |
| Bike descent | Stay controlled, fuel where safe and regain aero position on flatter roads. | Taking unnecessary handling risks. |
| Run | Start conservatively, then build after the first loop. | Trying to “make back” bike time immediately out of T2. |
Is IRONMAN 70.3 Mallorca good for a first 70.3?
It can be—but it is not the easiest first 70.3.
The swim is beginner-friendly and the run is flat, but the bike requires climbing strength and confident descending. If your bike handling is good and you have trained on longer climbs, Mallorca can be a fantastic first half-distance race.
If you are uncomfortable descending mountain roads or have done all of your preparation indoors, a flatter course may be more forgiving.
