For the first time, children can participate in the CORPUS Kidsrun over 2 kilometres for free. The organisation believes that children should exercise as much as possible and wants to promote this.

This is why the Leiden Marathon has decided to remove any financial threshold and allow children up to 12 years of age to run in the Kids Run on 11 May 2025 completely free of charge. However, they must officially sign up by registering at this website.

The CORPUS Kidsrun will form the spectacular conclusion of the event at 3pm.
