La bresl'oise - Bresles 2026

La Bresl'Oise is a trail running event held in June in Bresles, located in the Oise department of northern France. All races commence and conclude at the Halle de Plein Vent on Rue du General de Gaulle. The event features three trail races: a 24 km race with 480 meters of elevation gain, a 17 km race with 170 meters of gain, and a 10 km race also with 170 meters of gain. A walking option is available, making the day suitable for club runners, casual trail runners, and participants who prefer to walk. The courses begin at the event site, traverse sections of the town, and then enter the Bresles marshes and the Foret de Hez-Froidmont. The majority of the climbing for the longest race occurs within this forest area. Les PiedsMobiles are the organizers, and their stated aim is to foster a local and social atmosphere. This includes volunteer assistance, a barbecue, live music, an evening get-together, and a memento for every finisher. Records for the race date back to at least 2019, and AFIBUS is associated with the Bresles event program.
