Three trails. Three completely different challenges. One intense winter weekend. That is the Scott XTrails, the three-day trail concept of the Houffa Trail in Houffalize. During the Scott XTrails, it is not about a single race, but a full weekend of trail running. Participants line up at the start three times, each time presented with a different course and a different atmosphere. From a short but explosive opening stage to kilometers in the dark and a tough finale on Sunday.
