Koude Polderloop 2026

The Koude Polderloop begins and ends on Bellstraat in Nijkerk, directing runners into the open polder outside town. This is an annual road race offering three distances: 1 km for the youngest participants, and 5 km and 10 km for those seeking a flat challenge. The event is organized under Stichting Run033, with its operational structure linked to the Atletiekunie, the national athletics federation. The course is designed for speed, utilizing roads within the Nijkerk polders that are either closed to traffic or have limited access, avoiding a busy town center circuit. The 10 km route is officially measured and certified by the Atletiekunie, and the event provides certified 5 km and 10 km courses with electronic timing. Both recreational and competitive runners participate, with over 450 people reported in attendance. Wind and wet conditions are characteristic of the race, aligning with its name; this is a direct winter race across exposed polder roads, not a sheltered park run.
