The event in a few words

In June, head to the "Venice of the Alps" for a majestic sporting challenge. Located on the shores of Lake Annecy, the charming town of Doussard w welcomes you for its Half. Picture yourself starting this triathlon in the purest lake in Europe, the majestic Alps right in front of you 😍. With its 1.9 km of swimming, 85 km of cycling, and 21.1 km of running, this Half format offers a complete and demanding sporting adventure. Get ready to experience something breathtaking... in every sense of the word 😅. 

Every year, hundreds of triathletes meet up in Doussard to take on this extraordinary challenge. Amateurs seeking to push themselves or professionals chasing records 🏆, everyone comes together in a friendly, passionate atmosphere. Whether you’re a regular on the podiums or a challenger ready to try the adventure for the first time 🎯, this race is tailor-made for those who want to outdo themselves and push their limits 💥.

The start of this triathlon is from Doussard beach 🏖️. On the program, 1.9 km of swimming awaits you in the crystal-clear waters of Lake Annecy. No fickle waves or treacherous currents—just you, the clear water 💧 and a breathtaking view of the mountains 🏔️. You then continue with 85 km of cycling. The cycling leg starts gently with a fast, rolling section—ideal to warm up the legs 🚵‍♂️. But don’t celebrate too soon; the serious stuff arrives with the climb of the legendary Col du Marais 🏔️. This emblematic passage of the region will put your thighs to the test with its formidable gradients 🥵. Once over the pass, it’s time for a rolling profile that tests your endurance and effort management. Finally, to top it all off, you turn around and head back along the same road: you’ll go back over the Col du Marais, facing La Tournette, then over the Col des Esserieux before descending back to Doussard 😍. A real feast for the eyes (and a nice distraction to forget the muscle pain 💥). To finish in style, you wrap up your challenge with a half marathon that winds through the surrounding countryside, overlooking the lake. Your legs will burn 🔥, but the satisfaction of crossing the finish line in such spectacular scenery is worth every bit of effort in the world 😌.

The Half du Lac d'Annecy doesn’t just offer you an exceptional race: it also takes care of its finishers with a quality mega buffet. On the menu: crusty bread 🥖, smoked salmon 🐟, farm reblochon 🧀, fresh salad 🥗, fragrant tabbouleh 🌿, organic yogurts 🥛, fresh fruit 🍎… In short, a real feast to reward your achievements 😋.

Did you give it your all in this triathlon? Congrats! Now, time to relax and explore this magnificent region 🌟. If your legs are toast, it’s the perfect moment to try paddleboarding on Lake Annecy 🏄‍♂️. Too sore? You can always drift along in sunbathing mode 👙, but we won’t come looking for you 🤗. Then, head to the cobblestone alleys and the picturesque canals of this "Venice of the Alps". Stroll through the old town and sample local specialties like tartiflette or a crozets gratin 🤤. If that isn’t the definition of happiness after a triathlon, we don’t know what is! 😋

So, ready to make your Doussard ? We’re waiting for you—and this time, no turning back: you’ve already stepped into the arena! 💪

5 reasons to join this race

A dream setting for a major challenge 🏞️
Dreaming of combining sport and postcard-perfect scenery? The Half Iron triathlon in Doussard takes place at the foot of Lake Annecy, one of the чистest in Europe, with the majestic Alps as a backdrop. In other words, breathtaking scenery accompanies you on every kilometer of your race 😍.
A challenge that pushes you to outdo yourself 💪
The Half Iron format isn’t for fans of easy little strolls. With 1.9 km of swimming, 85 km of cycling, and 21.1 km of running, you’ll have to lay it all on the line 😅. On the bike side, 1,030 m of elevation gain and an out-and-back that makes you climb the Col du Marais twice ⛰️. But in the end, it’s the kind of challenge where you tell yourself: "I’m alive, and I’ve just accomplished something insane!" 🏅
A leg of the National Long-Distance Challenge 🏆
Organized since 2007 by Team Mermillod Triathlon, the Half du Lac d'Annecy is on the official FFTRI calendar. In 2027, it counts toward the National Long-Distance Triathlon Challenge 📋. Federation officiating, official rules, and a track record spanning nearly twenty years: you’re lining up for a proven staple of Alpine triathlon 🏔️.
A Half to experience solo or as a team 🤝
Not ready to chain all three disciplines in one go? The 2- or 3-person relay lets you share the effort: a swimmer for the lake, a climber for the passes, a runner for the half marathon 🏊. Only the first 10 teams get the €105 rate, so put your team together without waiting ⏳.
A king-worthy buffet to reward you 🍽️
We all know the best part of a race is after the finish line. And here, no simple cereal bar—no, no ✋. A mega buffet awaits you, with farm reblochon, smoked salmon, crusty bread, and fresh fruit. The dreeeeam 🤯.

A few more words

Splash! 🏊‍♂️ It kicks off strong with the swim leg, sending you diving into the crystal-clear waters of Lake Annecy, from the beach at Doussard 🌊. The course? A lovely 1.9 km triangle. No complicated geometry here—just you and a jaw-dropping view of the Alps 🏔️. Come on, swim straight and avoid the neighbors’ flailing arms, and it should go just fine! 😅

Hop, on the bike! 🚲 Now it’s time for the serious stuff: 85 km of pure bliss (and a bit of suffering, let’s not kid ourselves). The route starts off gently, but don’t be fooled: the Col du Marais is waiting for you ⏫, and it’s not here to mess around. With its legendary gradients, it’s going to test your thighs like never before 🥵. Once at the top, savor the descent and enjoy the view, because after the U-turn, here we go again: a second climb of the pass before heading back home 🚵‍♂️.

And we finish in style! 🏃‍♂️ You ditch the bike (finally 🙏) and roll straight into a half marathon through the surrounding countryside. Two loops to explore Doussard, Arnand, Marceau Dessus and Marceau Dessous (yes, that really exists) 😅.

So, ready to conquer this epic course? 💥
