Geneptrail Nocturne 2026

Geneptrail Nocturne is the meet-up where you swap the noise of everyday life for the silence of the mountains, and where your footsteps write a story in the night 🌙.

In L’Alpe d’Huez, in Isère, you enjoy a unique atmosphere: headlamps drawing a ribbon of light, the pure air of Auvergne-Rhône-Alpes, and that little thrill that makes you feel alive ❄️.

You choose your adventure: 9 km to treat yourself without overdoing it, or 18 km to fill your legs—and your eyes—with it 👟.

And if you come with the whole tribe, it’s even better: there are also kids & juniors courses, so everyone gets their share of magic (and so the youngest can gently tease you at the finish) 🧒.

After the line, stick around to extend the getaway: go gain some altitude at Pic Blanc, take a detour via Lac Besson for a quiet break, explore the landscapes of the Oisans valley, or head down to Bourg-d’Oisans for a stroll and a good hot chocolate on a terrace 🗻.

You’ll head home with your head full of memories, stars in your eyes, and only one desire: do it all again next year… ready to take on the night… with a beautiful stride? ✨
