Cancer affects us all. One in three people in Holland will develop cancer during their lifetime. Thanks to scientific research more and more people survive the disease. However, 45.500 people still die from the effects of the disease each year. We need money for scientific research, and this is where you can make a difference.


Do you want to make a difference in cancer research? Create your own fundraiser page. There is no minimum amount of sponsor money we ask you to raise. Do you raise more than 500 euro? You will receive the unique Run against cancer – shirt. Of course KWF will help you with raising money by providing tips, tricks and examples of other fundraisers.

Every individually registered runner will be able to keep their place in the rescheduled event as previously communicated.
