PRE-REGISTRATION FOR THE NN MARATHON ROTTERDAM 2026 For the upcoming edition, the NN Marathon Rotterdam is using a pre-registration for the marathon distance with equal chances for everyone. You can pre-register between September 9 & September 22, 12:00 noon. Registration for the other competitions will open later.

Run in the 45th edition of the NN Marathon Rotterdam, the fastest and also the most beautiful marathon in the Netherlands! The absolute world top as well as tens of thousands of runners from the Netherlands and abroad will finish on the heroic Coolsingel during the marathon weekend.

The NN Marathon Rotterdam is, due to the flat course, one of the fastest marathons in the world. The hundreds of thousands of enthusiastic spectators along the course provide a true celebration of sports and ensure that no other marathon in the Netherlands can match the atmosphere of #demooiste!

In addition to the sold out international marathon, which is also the Dutch Marathon Championships, on Sunday, April 12, there will be a program with various distances for young and old on Saturday, April 11.
