An autumn Sunday just the way we like them: a bit of a slope, plenty of mud, and above all, heart. Welcome to Gillonnay, in Isère, for a well-spiced edition of the Fête des Marrons. Two formats, two atmospheres, one shared goal: to enjoy yourself running among castles, chapels, and local warmth.

 

What you'll find on-site:

  • Two adult races to choose from: a 9.9 km cross-country race to warm up your legs (and thighs), or a trail of 20 km to take in the scenery and tackle some elevation gain;
  • Children's races to introduce the little ones to the big thrills of the starting line;
  • A souvenir gift, well-placed refreshment stations, and a medal worthy of your display cabinet (or your glove compartment, depending on your style).

 

Course focus:

The Cross des Marrons is short, but feisty. Ideal for fans of rhythm and surges, it'll push you into the red faster than a roasted chestnut at aperitif time. The perfect opportunity to test your MAS between the Isère countryside and a local village fête atmosphere.

The Trail des Châteaux & Chapelles, on the other hand, immerses you in scenery that is anything but rustic in its charm. Between wooded paths, high points, and monuments dotting the route, you'll have plenty to feast your eyes on. No poles needed here: your legs and willpower will be enough to guide you to the finish arch.

 

3 good reasons to take part:

  • Challenge yourself on accessible yet demanding formats, whether you're a weekend runner or a seasoned Saturday trail runner;
  • Enjoy a true village race, organised with heart by the Entente Athlétisme Gillonnay-La Côte club. Here, we run, we laugh, we share.
  • Leave with a little taste of chestnut in your mouth and a big smile on your face. Yes, that's also the magic of autumn in Isère.

 

Are you coming? The atmosphere promises to be as warm as the soup at the finish line stand.
