The DNF 2026

In Andilly, in the Val-d’Oise, The DNF offers you a trail race that stands out from the crowd: here, you come for the adventure, the atmosphere, and that little Halloween thrill 🎃.

The concept is simple and terrifyingly effective: you choose your format 3h, 6h or 12h, you move at your own pace, you challenge yourself, and you surprise yourself wanting “just one more lap”… until the forest reminds you that the night has its own character too 🌲.

Want to share it? Take the relay option: you run, you cheer, you laugh, you push each other on, and you discover that the best fuel is the team 🤝.

And if you come with family, it’s even better: there are kids & juniors courses, and the Fun Zombies format wins everyone over for a dose of fun that makes hearts beat a little faster… so, will you try your luck or let the zombies win? 🧟

After the effort, stay nearby to make the most of it: pop over to L’Isle-Adam to enjoy the banks of the Oise, stop by Auvers-sur-Oise for the atmosphere, or treat yourself to a walk in the Montmorency Forest to recover surrounded by nature.

And if you want a simple, perfect end to the day: head to Enghien-les-Bains for a stroll by the lake and a drink on a terrace—just the thing to tell “your” DNF like a true local legend 🥤.
