Your race makes a difference
Every 5 minutes, someone in the Netherlands is diagnosed with cancer. In that same time, you run 1 kilometer. Whether you get it yourself or someone you care about; cancer disrupts your life. KWF is committed to reducing the impact of cancer.

We give you the chance to turn the powerlessness you may feel when touched by cancer into strength. Run against cancer, raise money for important cancer research and contribute to KWF's mission: Fewer people diagnosed with cancer, more people cured and more people living better with and after cancer.

During previous editions we already raised almost 4 million euros. Your race can really make a difference. Will you join us this year?
