Race day for this edition — 12 July 2026 — has passed. The guide stays up for reference.
Upcoming race guides →IRONMAN 70.3 Versailles is a single-transition 70.3 in the grounds of the Château de Versailles — you rack once on the Allée des Mortemets, with colour-coded bags for the bike and the run, and your bike goes in the day before. The swim is in the Pièce d'Eau des Suisses, the finish is on the Avenue de Paris, and here's exactly what goes in each bag.
Bike and run turn through one transition on the Allée des Mortemets — you come back to the same rack between disciplines. But the day is spread across the grounds: the swim is in the Pièce d'Eau des Suisses, and the finish is on the Avenue de Paris, roughly a 35-minute walk from the rack. Your white bag bridges the start and the finish for you.
IRONMAN's colour-to-bag scheme is the same across European 70.3s, so this part is settled. Pack each bag for the discipline it powers — and for a warm, long mid-July day in the Chevreuse Valley.
Versailles runs a mandatory day-before bike check-in on the Allée des Mortemets with the bike and transition bags racked overnight — there's no race-morning bike check-in to fall back on. Bike and bags check-in runs Saturday afternoon and closes at 19:00, and it's where you collect your timing chip.
The 2026 official guide is in. The times below are now confirmed for this edition — a few moved from last year.
The choreography barely moves year to year — transition opens at 06:00, the white street bag goes in at the swim start by 07:35, the bike park closes at 07:00, then the rolling swim start in the Pièce d'Eau des Suisses. The order is what matters.
The blue bag is your bike / T1 bag — helmet, bib on a race belt, bike shoes, sunglasses and ride nutrition. It's racked with your bike on the Allée des Mortemets the day before, and you use it to stow your wetsuit and swim kit in T1.
Your white street-wear bag is dropped at the swim start and moved to the finish on the Avenue de Paris, where you collect it in the after-finish area. You can leave it until 07:35 on race morning. The rack itself is about a 35-minute walk from the finish, so the white bag is how dry clothes reach you.
Yes. Bike check-in is mandatory and day-before, with the bike and transition bags racked overnight on the Allée des Mortemets. Bike and bags check-in closes at 19:00 on Saturday, and there is no race-morning bike check-in — so don't plan to bring it on the day.
Three: blue for the bike, red for the run, white for street wear. It's a single transition, so blue and red both sit at the one rack; the white bag is moved from the swim start to the finish for you.
The 1.9 km swim is in the calm Pièce d'Eau des Suisses at the foot of the Château, with a self-seeded rolling start. T1 then has a long stretch on foot from the swim exit to the bike — keep your wetsuit on through it, lowering the top to your waist if you want, and peel it off at your rack.
The 90 km loops the Chevreuse Valley with around 772 m of climbing — punchy hills like the Côte de la Vacheresse and the 17 Tournants rather than long mountain passes. Pack ride nutrition and sunscreen in the blue bag, with light gloves for the faster descents on a warm July day.
