L'Onessoise 2027

In Onesse-Laharie, you come looking for a race, and you leave with a real breath of fresh Landes air 🌲.

L’Onessoise is the kind of meet-up where the forest takes you by the hand and every trail whispers “just one little detour more” 🧭.

You choose your adventure: 5 km to treat yourself without burning out, 10 km to savour it longer, 12 km to enjoy a bit more, and a kids’ race so the mini-explorers get their moment of glory too 🏅.

And after the effort, keep the good times going close to the start: pop over to Contis-Plage to breathe in the ocean air, climb the Contis lighthouse for a view that sets your head straight, stop by Lit-et-Mixe for a laid-back stroll, or head to Saint-Julien-en-Born for a salty little escape—walks and sunset vibes 🌅.

Come for the trails, stay for the atmosphere, and leave with memories filling your trainers (and not just sand) 🥾.
