Isoniq Urk Marathon

The Isoniq Urk Marathon begins and ends at the harbor in Urk. Runners depart beside the IJsselmeer during autumn. This road race offers a full marathon and a half marathon. The full marathon is presented as Flevoland’s sole marathon. The course is paved, certified, and designed for speed, not trail running. The route follows Urk’s historic boulevard toward the dike, then consists of repeated laps: four for the marathon and two for the half. Loopgroep Urk, affiliated with Atletiekunie, organizes the event. Entry limits are 500 marathon runners and 200 half marathon runners, making it a focused local race instead of a large city marathon.
