The event in a few words

Don’t loop miss out ✅.

Get your calves and your best smile ready, because in addition to Courchevel, La Rosière, Morzine or Courmayeur, the crazy MDS Crazy Loops concept is landing in Val-d'Isère at the end of summer for an edition in the heart of Savoie that already promises to be legendary 🤩. The goal is as simple as it is addictive: you have 3, 6, 9, 12 or 24 hours to rack up as many loops as possible on a route of to 5 km📍. If you’re a dedicated runner, you’ll recognize the backyard 🔄 concept—except you’re not required to head back out every hour 🕘. Basically, it’s the pure DNA of the Marathon des Sables dropping in at over 1800 m of altitude for a challenge where you run, you walk, you stop to wolf down a slice of Beaufort, and you set off again under a breathtaking starry sky 🌌. The month of August won’t be restful, we’ll grant you that 😮‍💨.

As a ski and mountain lover, you probably already know the resort of Val-d'Isère, just a stone’s throw from the border with Italy and hugely popular with outdoor athletes 😍. Located near the Tsanteleina summit and with Mont Blanc in the background, you’ll be able to treat yourself to a true timeless escape between dizzying ridgelines and sunlit alpine pastures 🐑, where the effort almost becomes secondary to the beauty of the show 🤩. But the real magic of the Crazy Loops lies in its supportive and inclusive 🫂 spirit. You share the trail with Para-sport teams, which means you can help them, accompany them, and even help them get up a climb 🥵. On a steeper section, a technical descent, or simply for the joy of sharing, you can at any moment join a Handi team and help out 💪. That’s the beauty of sport 😍. Between loops, the race village becomes the beating heart of the party—you’ll build unique bonds to make it to the end of the adventure 👯‍♀️. To experience it to the fullest, you have two options: the bivouac package with two nights under an MDS tent, or the self-sufficient package if you prefer to bring your own tent or book accommodation 🏠. Whether you choose to sleep under the stars or get cozy after your feats, the atmosphere will remain festive, alpine, and resolutely laid-back 🧘. You run, you walk, you push yourself to the limit, you lift others up, you stop… and you set off again until you’re wiped out 🥱.

Once you’ve completed your 42nd loop (or your 2nd—it’s up to you 😌) and your calves are begging for a break, the adventure continues 💥. Since you’re already perched up in Val-d'Isère, take advantage of the fact that your legs still work (a little) to go say hello to our neighbors across the Alps ↔️. Italians are widely known for their tasty dishes, but their mountains have nothing to envy compared with France’s highest peaks either 🇫🇷. Monte Rosa or Punta Perrucchetti will leave you with some incredible memories of the region 🏔️. If your joints are crying for mercy, you can also try natural cryotherapy 🥶 by dipping your feet into an icy alpine stream. It’s local, it’s free, and it’s brutally effective at putting out the fire smoldering in your shoes 🔥. And between two slices of Savoie ham and a diot sausage in white wine, don’t forget to dip your bread into a generous fondue —even in the middle of summer, it goes down just fine! 🫕

In August, come wrap up your summer season in Val-d'Isère! 😵‍💫

4 reasons to join this race

The concept 🔄
It’s absolute freedom! You manage your effort however you like for 3, 6, 9, 12 or 24 hours 😍. A 3 to 5 km loop, to be done twice for fun or twenty times for the challenge. You decide when you stop to dance or when you jump back into the fight 👊. You hold the cards—your move 🥵.
An inclusive and supportive adventure 🫂
MDS Crazy Loops lets you become a Helping Runner to bring meaning back to your stride ♿. Sharing the course with the Handi teams and helping each other on the steep sections creates a unique bond you won’t find anywhere else in competition. That’s what the true values of sport are all about, right? ❤️
Sharing the effort over several days ⛺️
You’ll spend two nights in a base camp alongside your adventure buddies 👯‍♀️. You’ll share your strides, your doubts and your belly laughs with strangers who quickly become your best allies (or rivals 😈). It’s this repetition of effort over several days that turns a simple sporting performance into an unforgettable memory etched in 💪. It’s the perfect chance to disconnect from everyday life and reconnect with what matters: the joy of moving forward together.
An Italian-style getaway 🤌
Since you’re heading deep into the French mountains, make the most of the trip and extend your stay 🧳. Italy is within easy reach and just waiting to be explored. Once you cross the border, you’ll find yourself in the "Gran Paradiso National Park". How can you not get excited by a name like that? 🤩
