IRONMAN 70.3 Aix-en-Provence 2027
A lake swim at Peyrolles, a deceptively lumpy bike through Provencal back roads, and a run finishing on the Cours Mirabeau in Aix.
40 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Build my complete road.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“A hillier bike than the Provence postcards suggest, and it often gets hot. Fuel and cool early rather than reacting when you are already cooked.”
The race
The course
IRONMAN publishes no route file for this leg, so there is no course map to draw from.
A rectangular loop of Lac de Peyrolles, which sits 20km outside Aix. The swim is not in the town you race the rest of the day in, so read the logistics carefully: bikes go down the day before and there is a shuttle on the Saturday.
One loop back towards Aix, mixing flat road with genuine climbing and the technical roads around Mont Sainte-Victoire. Technical means the descents cost you time if you are timid and skin if you are not.
Three loops through the middle of Aix, its parks and around the Rotonde fountain, finishing on the Cours Mirabeau. Town-centre laps, so you will pass the finish twice before you are allowed it.
Not yet confirmed for this edition: bike elevation gain, aid station spacing, water temperature. We publish these only once they are on the official course page, so check there before you pace off anything here.
