Where it is
AIX-EN-PROVENCE, FRANCE
Is this your race?
This is a genuine half-iron challenge set against one of Europe's most spectacular backdrops. The lake swim is calm and wetsuit-friendly, and May weather in Provence is famously kind — but the bike course climbs roughly 1,180 m through the hills around Sainte-Victoire, and the overall cut-off of 8 h 30 min means you need a solid aerobic base before you toe the line. Beginner fit 3/5: Half-Ironman baseline 3, −1 for bike climbing above 1,000 m, −1 for water temperature below 18 °C, +1 for sheltered calm lake swim with wetsuit likely, +1 for mild spring weather.
✅ You’ll love it if…
- You have completed at least one Olympic-distance triathlon and want your first 70.3
- You enjoy hilly cycling and have been training on climbs
- You want a race with a stunning finish in a historic French city
- You thrive in mild, dry spring weather (typically 14–24 °C)
⏳ Build up first if…
- You have never ridden more than 60 km or climbed more than 800 m in a single ride — add dedicated hill sessions first
- Open-water swimming is new to you — get comfortable in a lake or reservoir before race day
- You are not yet confident finishing a half-marathon after a hard bike effort — brick workouts are essential
- You need more than 8 h 30 min to complete a 70.3 at your current fitness

The course, demystified
The race spans two venues roughly 20 km apart: the swim and first transition sit at Lake Peyrolles in Peyrolles-en-Provence, while the second transition and finish line are in the heart of Aix-en-Provence. Plan your logistics around this split. Note: the 23 May 2027 date is listed in federation records but has not yet been confirmed on the official IRONMAN race page — verify at ironman.com/races/im703-aix-en-provence before booking.
Respira y flota (breathe and float) — the start is a rolling entry into Lake Peyrolles, a calm freshwater lake. One loop, no surf, no current to fight. Water temperature is reported around 17–18 °C, so a wetsuit is very likely permitted and strongly recommended. A rolling start means you seed yourself by expected swim time and enter in small groups, which keeps the early chaos to a minimum.
The bike rolls out of Peyrolles-en-Provence through the Pays d'Aix countryside and loops around the iconic Sainte-Victoire mountain. The course passes through roughly eight surrounding towns, so expect enthusiastic roadside support. The climbing — approximately 1,180 m in total — is the defining feature of this race. Grades are typical of Provençal roads: sustained rather than brutal, but relentless if you go out too hard.
The run is a three-loop course through Aix-en-Provence, mixing city streets with the green paths of Parc de la Torse. Reported elevation is around 188 m — rolling rather than flat, but manageable compared with the bike. Three loops mean you pass the finish area multiple times, which is a psychological double-edged sword: great for crowd energy, tough when your legs are asking you to stop.

How to fly in
Nearest airport details were not verified in our research — check the official race page at ironman.com/races/im703-aix-en-provence for recommended gateways. Marseille Provence Airport (MRS) is the closest major hub to the Aix region and is worth checking first. Allow at least a day of buffer after arrival before race registration.

Where to stay — by what matters to you
Aix-en-Provence
The second transition and finish line are here, so staying in Aix puts you close to race-week buzz, athlete check-in, and the finish-line celebrations. Excellent restaurants and cafés for carb-loading. Expect higher demand and prices during race weekend — book early.

Bringing a support crew?
The two-venue format actually works in spectators' favour: you can watch the swim start at Lake Peyrolles, then drive or take transport into Aix to catch the run and finish line — two completely different atmospheres in one day.
- Lake Peyrolles swim start and T1 — watch athletes enter the water and emerge for the bike leg
- Roadside on the bike course — the route passes through roughly eight towns in the Pays d'Aix; check the official course map for spectator-friendly spots
- Parc de la Torse, Aix-en-Provence — the run loops through this park, giving multiple viewing opportunities per lap
- Finish line in Aix-en-Provence — the city-centre finish is the best place to be; arrive early for a good spot as the day progresses
