10K Zorg en Zekerheid sold out

The 10K Zorg en Zekerheid is sold out. Unfortunately, there are no more race entries available for the 10 kilometres on May 10, 2026. So there is absolutely no point in contacting the Leiden Marathon organisation, as there simply are no more tickets available. Switching from another distance to the 10 kilometres is unfortunately not possible either. The 21K Bunnig & Partners had already sold out earlier.

The only option is to acquire a race number from someone who unexpectedly cannot start, via our own Resale Platform. You can then change all details yourself. This is possible until May 1 at the latest. Payment must be arranged between yourselves. Click here for our Resale Platform: https://platform.inschrijven.nl/2026051007901

And NOTE: we do not support race numbers offered through any other channels (Marktplaats, Facebook, etc.) in any other way. Furthermore, scammers are sometimes active offering race entries they do not actually possess. Be on your guard for this.
