Course & Elevation
The Rotterdam Half is a new half marathon in Rotterdam, first run on Sunday 20 September 2026. It was sold out within a quarter of an hour, and 7,000 runners started after about 25,000 people asked for a place in the pre-registration. The race starts at 09:00 at the Maassilo on Rotterdam-Zuid and finishes inside Rotterdam Ahoy; the organisers originally planned a start and finish at the Maassilo but moved the finish for safety reasons when the field grew. The 21.1 km route is described as flat, fast and officially certified. It goes over Katendrecht past the SS Rotterdam, into the port area via Brielselaan, Sluisjesdijk and the Waalhaven quays, then through the Wielewaal district and the Zuiderpark to the finish at Ahoy. The organiser is Faive Running together with Rotterdam Running Crew. The organisers aim to grow to about 15,000 participants within five to ten years. The organiser's site invites runners to join a waiting list for the next edition, but no 2027 date has been announced.
