De ZorgSpecialist Grachtenloop 2026

Runners navigate Haarlem’s canals and city-center streets during De ZorgSpecialist Grachtenloop, a Friday evening midsummer run in the Netherlands. It offers 1 km, 5 km, and 10 km options, accommodating participants from short-distance runners to those completing the full city loop. Recent editions have attracted over four thousand participants, with entry capped rather than open-ended. The route stays near the Haarlem grachten and proceeds through the historic center, lending the event its name. SportSupport organizes the race, affiliated with the Atletiekunie. De ZorgSpecialist has sponsored the event for seven years. The evening concludes after the finish with refreshments and a DJ at the Koepelterrein. Organizers also provide practical amenities like lockers and heat measures when midsummer weather necessitates them.
