De Jong & Laan Halve Marathon Oldenzaal 2026

The De Jong & Laan Halve Marathon Oldenzaal is an autumn running event held annually in Oldenzaal, Overijssel. The half marathon is the primary race, complemented by 10 km, 5 km, and youth 1 km and 2 km races. A business run and a school championship are also part of the event, broadening participation beyond just half-marathon competitors. Early registrants receive their start numbers by mail, while later entrants pick theirs up at the venue. During the LAAC Twente era, the race was known as the Halve van LAAC and utilized the outskirts of Oldenzaal. As development encroached on that area, organizers relocated the course towards Weerselo, eventually introducing a new route and the name Huttenkloasloop. That iteration guided participants through the scenic, undulating countryside surrounding Oldenzaal, bearing the motto “Not the fastest, but the most beautiful!” The event is now named Halve Marathon Oldenzaal, retaining the same route, and is managed by Stichting Halve Marathon Oldenzaal. De Jong & Laan serves as the main sponsor, and the event contributes to Kans voor een kind.
