We are proud to announce that the participant limit for the 47th Nationale-Nederlanden Warsaw Marathon has been increased to 13,000 runners. This milestone will make the 2025 edition the largest marathon in Polish history — and the first ever in Poland to surpass 10,000 participants. It also positions Warsaw among the leading marathon events in Central Europe.

What makes Warsaw special? It’s a city full of passionate spectators (just ask those who ran the half marathon!), and now it features the fastest course in the history of our event — one of the fastest in Europe. This is your chance to be part of something truly exceptional.
