Whole courseGeometryOut to the coast by the Zeeweg, home through ElswoutReversed in 2025, starting on the Nieuwe Gracht and finishing on the Grote Markt.
In 2025 the organiser moved the start of the half marathon from the Grote Markt to the Nieuwe Gracht and turned the route around. Runners first go along the Zeeweg towards the coast and come back towards the city past Kraantje Lek and Elswout. The finish stays on the Grote Markt, in the middle of the old town. The 2026 report adds that the reversed direction keeps runners from getting in each other’s way at the Houtmanpad, and that the start on the Nieuwe Gracht goes off in waves.

The organiser calls the race the biggest running party in Haarlem, with entertainment all along the route. At the 40th edition on 27 September 2026 a walking DJ worked the cheering zone on the Houtmankade, and there were more zones at the Zijlbrug, Brouwerskolkje, the head of the Zeeweg, Kraantje Lek and the finish. Spectators lined the rest of the route with signs.
