Trail de Bruxelles 2026

Trail de Bruxelles is a forest trail race held in the Zoniënwoud, near Brussels, beginning at the Oudergem sports center. It takes place in October and features four marked distances: 10 km, 15 km, 20 km, and 25 km. This event emphasizes trail running over road racing, with over 90% of the terrain unpaved and each route forming a single loop through the forest. The shortest distance includes 178 m of elevation gain and a two-hour time limit, while the 25 km route has 374 m of climbing, two aid stations, and a 3 hour 45 minute limit. The courses are marked with clear signs displaying black arrows, and marshals are stationed at intersections and hazardous sections. Runners operate in semi-autonomy, carrying their own supplies between aid stations, which offer water, energy drink, and snacks. The race eschews disposable plastic cups, requiring participants to use their own cup or bottle, or an eco-cup. Recent events have attracted approximately 1,500 participants. The organization is functional: bibs are distributed on race day, showers and changing rooms are provided, bag storage is organized by race number, parking near the sports center is restricted, and dogs are permitted on the course but not within the sports center itself.
