Vlaamsyard : Le Défi des Géants - Cassel 2027

Vlaamsyard: Le Défi des Géants is a 25-hour Backyard-style endurance race in Cassel, Flanders. Participants must be 18 or older and run a 6.5 km loop with 250 m of elevation gain per lap. The event is limited to 200 runners, making it a focused competition. The course is intentionally repetitive, featuring a single circuit with consistent terrain and climbs. This design emphasizes pacing, nutrition, mental fortitude, and managing the psychological challenge as fatigue and darkness alter the perception of the loop. The organizer provides aid stations, parking, restrooms, showers, a participant gift, and a medal. The most determined runners target 100 miles, involving approximately 6000 m of climbing.
