Trail de la Foulerie

Step into early October for an invigorating trail experience just one hour from Paris by public transport. The small village of Chaumont-en-Vexin, nestled in the western part of Oise, invites runners to break free from their daily routines and embrace a weekend filled with fresh air and scenic trails.
Organized annually by the town hall of Chaumont-en-Vexin as part of Pink October, this year’s Trail de la Foulerie offers participants an opportunity not only to challenge themselves physically but also to support women affected by cancer. The event features three distinct courses: a 7 km trail for newcomers, a more challenging 12 km route that caters to regular runners, and a full marathon of 23 km designed for seasoned trail enthusiasts.
The shorter 7 km course is ideal for those looking to dip their toes into the world of trail running. It offers gentle elevation changes through lush forests, providing an introduction to the beauty and challenges of natural terrain without overwhelming first-timers. The 12 km loop, meanwhile, takes runners on a zigzagging journey between pine trees and babbling streams, with over 240 meters of climb that will surely get hearts racing.
For those who crave more adventurous routes, the 23 km marathon is perfect for trail running enthusiasts eager to push their limits. This longer course winds through stunning valleys and past ancient castles, offering breathtaking views at every turn while providing a significant challenge with its elevation gains.
Beyond the race itself, Chaumont-en-Vexin offers rich cultural experiences that complement this athletic endeavor. Start your day by visiting Saint-Jean-Baptiste Church or Château de Bertichères—two 16th-century landmarks that stand as testaments to history and architecture. After crossing the finish line, take time to explore these historic sites and immerse yourself in the local culture.
The Trail de la Foulerie is more than just a race; it’s an event rooted in tradition and community spirit. Named after Place de la Foulerie—the village square where flax from surrounding fields was once trampled—this trail run celebrates both its historical heritage and modern-day purpose of raising awareness for women's health.
Join us on October 11, 2026, to lace up your running shoes in support of a noble cause. Whether you’re looking to challenge yourself physically or simply enjoy the beauty of nature and history, Chaumont-en-Vexin awaits with open arms.
