's Gravenvoeren, Belgium, 24 Oct 2026

This course runs through the Voer region, reaches the Three-Country Point, and includes a loop through the Preuswald before returning to the finish in 's Gravenvoeren. The organiser presents it as a very technical route with mountain trails, singletrack, a high off-road ratio, and demanding climbs that make it their biggest and toughest trail. It is the flagship ultra of the Bear Trail weekend, and recent editions have sold out well in advance.

One distance, 100 km, up to 3,087 m of climb.
