Wase Marathon 2026

The Wase Marathon takes place at OC Troelant in Sint-Niklaas, East Flanders, offering races of various distances rather than a single marathon. The event includes a 5K Bokkenrun, 10 miles, a half marathon, and a 58 km ultramarathon, catering to local runners seeking shorter races and those desiring a long trail-style challenge. The courses traverse the Waasland countryside via rural and regional paths, described by organizers as a run through Wase nature. Running Team Sinaai vzw manages the event with volunteer support for marshalling, aid stations, catering, registration, and the finish area. The club has been recognized as Sint-Niklaas’s Ambassador of Sportiness by the city and sports council, reflecting the event's club-organized, community-focused character.
