The Strong Viking Obstacle Run Hofstade, a mud-and-obstacle event, is held at Tervuursesteenweg 395 in Zemst, Belgium. Race options range from a 4 km family route to a 60 km ultra. The shorter distances accommodate children and beginners. The 42 km Iron Viking includes over 100 obstacles, and the 60 km Ultra Viking features more than 135 obstacles.
The course incorporates mud, aid stations, and specific obstacles like Storm the Castle, Mud Trenches, and the Strong Viking SAGA’s. Many obstacles offer a walk-by option, though OCR Series participants adhere to different obstacle rules. All finishers get a Strong Viking Finisher T-shirt. Personal race photos are available, and spectators are welcome to watch without charge. Runners may check one bag at a guarded cloakroom; lockers are not provided.
