The event in a few words

Samantha Loops ! 🤭

Get your calves and your best smile ready, because in addition to Courchevel or La Rosière, the crazy concept of MDS Crazy Loops is coming to Courmayeur in June for an edition that already promises to be legendary in the heart of the Aosta Valley in Italy 🤩. 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 to 5 km📍 course. If you’re good at deduction, you’ll recognize the backyard 🔄 concept—except you’re not required to start again every hour 🕘. Basically, it’s the pure DNA of the Marathon des Sables showing up at altitude for a challenge where you run, you walk, you stop to admire Mont Blanc, and then you set off again under a breathtaking starry sky 🌌.

If you love trail running and the mountains, you probably know Courmayeur, a key checkpoint of the UTMB 😍. Running facing Mont Blanc with Italy as your playground means treating yourself to a timeless break between dizzying ridgelines and sunlit alpine pastures 🐑, where the effort almost becomes secondary to the beauty of the show 🤩. But the real magic of Crazy Loops is its supportive and inclusive 🫂 soul. 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 just for the joy of sharing, you can at any time join a Handi team and help them 💪. That’s the beauty of sport 😍. Between loops, the race village becomes the beating heart of the party, and you’ll build unique bonds to make it to the end of the adventure 👯‍♀️. Another piece of good news: our four-legged friends are welcome in the race 🐕. To live the full experience, you have two options: the bivouac package with two nights under an MDS tent, or the self-sufficient option 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 decidedly laid-back 🧘. You run, you walk, you push yourself to the limit, you pull others upward, you stop… and you set off again until exhaustion 🥱.

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 💥. Visit the Courmayeur Alpine Museum, recover at the heated alpine pool at Plan Chécrouit, or hop on the Skyway Monte Bianco cable car ⬆. If your joints are crying for mercy, you can also try natural cryo 🥶 by dipping your feet in an icy alpine stream. It’s local, it’s free, and it’s radical for putting out the fire smoldering in your shoes 🔥. Enjoy Valdôtaine cuisine by tasting polenta, fontina, carbonade (not to be confused with carbonara), and torta di nocciole for a sweet touch 🥧.

Ready to run yourself ragged? 😵‍💫 Don’t loops this event!

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 do twice for fun or twenty times for the challenge. You decide when you stop to dance or when you head back into battle 👊. The cards are in your hands—your move 🥵.
Sharing the effort over several days ⛺️
You’ll spend two nights in a base camp alongside your adventure buddies 👯‍♀️. You share your strides, your doubts and your laughter with strangers who quickly become your best allies (or competitors 😈). It’s this repeated effort over several days that turns a simple athletic performance into an unforgettable, lasting memory 💪. It’s the perfect opportunity to disconnect from everyday life and reconnect with what matters: the joy of moving forward together.
An inclusive and supportive adventure 🫂
MDS Crazy Loops lets you become a Helping Runner to give more meaning to your stride ♿. Sharing the course with Handi teams and helping each other on steep sections creates a unique bond you won’t find anywhere else in competition. That’s the beautiful values of sport, right? ❤️
A panorama facing Mont Blanc ⛰️
Running in Italy through one of the towns passed by the world’s most famous trail race is simply fantastic 😮. It’s the ideal spot to fill your memory bank with alpine landscapes that look like they came straight out of the movie Heidi 🤩.
