Qbuild Arlon Marathon 2026

The Qbuild Arlon Marathon begins at the Palace on Place Léopold in Arlon, the capital of Belgium’s Luxembourg province, near the Luxembourg border. This mid-September road race offers 10 km, half marathon, full marathon, and a four-person marathon relay. The course loops through Arlon; half-marathon participants complete it once, and marathon runners complete it twice. The route combines town streets with natural areas, extending beyond the city center. The event is relatively new, and its initial years are significant as Arlon had not previously hosted both a marathon and a half marathon in its capital city. Local authorities, police, technical services, partners, and volunteers support the event, while food stands and music provide entertainment for spectators awaiting the finish.
