The Halve Marathon Zoetermeer begins and ends at the Dekker Zoetermeer grounds. The half marathon starts at 11:30, with the shorter main races commencing at 12:30. This January road race in Zoetermeer offers four distances: a 1.5 km Kids Run, 5 km, 10 km, and the 21.1 km half marathon. Participant numbers are limited to 2,000, making it a local event suitable for families, club runners, business teams, adapted-sport athletes, and walkers, rather than a large city marathon.
The course crosses Zoetermeer, Pijnacker, and the Balijbos. It is described as fast and compact, with decorations in the race area. Custom Made Sport is the organizer, and Dekker Zoetermeer provides essential race-day amenities like parking, catering, and warm showers. A dedicated Kids Run is available for children, primary schools can compete in the School Competition, and Powerwalking is an option for those not wishing to run. This race is one of three significant running events promoted in Zoetermeer, alongside the Klaverbladloop and Geuzenloop.
