The Lowdown
The Arlon Semi-Marathon is a half marathon in the town of Arlon, in the province of Luxembourg in Wallonia. The 5th edition ran on September 13, 2026 as the Qbuild Arlon Semi-Marathon, and the next edition is expected on Sunday, September 12, 2027. Start and finish are at place Léopold. The course was reworked so every runner covers a single loop, passing the Arlon golf course, Camp Lagland and the traffic-free city center. A 10K and a children's run of about 1.5 km start the same morning. In 2026 entry started at 25 euros for the first 200 registrations, and 2027 pricing is not yet published.
