About the Event

Get ready for a muddy, adventurous escape into the woods near Paris at the Trail des Marcassins on Sunday, January 25, 2026. Celebrating its 15th anniversary, this classic winter trail run, starting in Saint-Brice-sous-Forêt, plunges you straight into the heart of the Montmorency Forest with a choice of a challenging 30 km or a more accessible 15 km loop. Be prepared for a true self-sufficient adventure on wet, muddy, and technical paths where you might even spot wild boar (marcassins) among the trees, all just a short distance from the urban buzz of the capital.

In keeping with its commitment to preserving the forest ecosystem, the event is proudly cupless, so you must bring your own reusable vessel for the single aid station. Embrace the cold, the mud, and the camaraderie of this beloved local tradition that tests your agility and spirit, offering a perfect dose of wild nature and a fantastic, messy start to your trail running year.
