KWF – Running against Cancer
For this 41st edition, the NN Marathon Rotterdam is again supporting the KWF Kankerbestrijding. Fewer case of cancer, more cures and a better quality of life for cancer patients. That is the aim of KWF Kankerbestrijding. Participants can make a difference by adding a donation to KWF when they register and/or creating a campaign page with KWF. Additionally, KWF is running a unique action. When participants register for the ¼ Marathon Rotterdam or the full marathon through KWF and raise at least €500 worth of sponsoring before the 1st of February 2022, they will be rewarded with a free bib number and the unique “Ren tegen kanker” T-shirt.

Approximately 50,000 runners in total are expected to take part over the marathon weekend. There is a cap on the number of participants for the NN Marathon Rotterdam and ¼ Marathon Rotterdam. The expectation is that, as was the case in previous years, these two very popular distances will sell out very quickly.

Obviously, we will follow the COVID-19 developments closely and will take alle necessary measures. If the event were to be cancelled unexpectedly and cannot take place on 9 and 10 April 2022 due to COVID-19, all purchased bib numbers will remain valid for the following edition.
