46 km trail
The itinerary in detail
The 46 km route is intended for experienced trail runners, even though the elevation gain is reasonable. It plunges into the Sonian Forest via some beautiful single tracks, skirts around the magnificent Château de La Hulpe, and crosses several nature reserves and remarkable sites before bringing you back to the Uccle-Boitsfort racecourse. A surprising route in the heart of the green lung of the European capital.
Upon your arrival, the finish village will be transformed into a welcoming venue to greet you and extend the enjoyment beyond the race.
