Run against Cancer

Your race makes a difference
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, 45.000 people still die from the effects of the disease each year. With your participation in the NN Marathon Rotterdam you can make a difference for everyone affected by cancer.
