Course & Elevation
The NN Marathon Rotterdam is a city marathon held on a Sunday in April, as the centrepiece of a two-day running weekend. The first Rotterdam marathon was run on 23 May 1981 with just over 200 starters, and the 2027 race on 11 April is the 46th edition. It is organised by Golazo together with the municipality of Rotterdam. The marathon starts on the Schiedamsedijk at the foot of the Erasmusbrug; until 2017 it started on the Coolsingel. Straight after the start runners cross the Erasmusbrug towards the Kop van Zuid and the south of the city, pass Stadion Feijenoord and Ahoy, and cross the bridge again. In the last kilometres the route makes a loop around the Kralingse Plas, passing the Cube Houses and the Markthal, before finishing on the Coolsingel. The course is officially measured. The same Sunday has a 10 km race and the Dutch marathon championship, and the Saturday has a programme of other distances for all ages. The course records are 2:03:36 for men, set by Bashir Abdi in 2021, and 2:18:56 for women, set by Mekides Shimeles in 2026.
