School campus

On April 12, Stadhuisplein will be transformed into a school campus with market stalls. Here you can gather as a school and leave your belongings. When you register you can indicate whether you want a free stall, this is possible from 50 participants.

The exits after the finish of the NN Kids runs are divided into 4 colors and shapes that correspond to the colors on the bib numbers and wristbands. The coaches of groups with more than 50 participants can then welcome their children in the designated area and walk back to the School Campus via a separate exit. This exit is indicated with colors and figures that correspond to the bib number and wristbands.

Purchase your bib number via NN Marathon Rotterdam and create a campaign page at KWF. With your own Run Against Cancer campaign page, fundraising is easier than you think. Every euro counts! Will you raise 500 euro or more? Then you will receive the unique Run Against Cancer shirt. Ofcourse, KWF supports you in collecting donations, with tips, tricks and great examples of activists who came before you.
